The 05-07 Buick Terraza 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW216 (Part #HBCW216) fits 2005-2007 Buick Terraza models. The 2007 model year is the last year covered by this part number. For newer models, check for an updated version.
The 05-07 Buick Terraza 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW216 (Part #HBCW216) fits the following vehicles: 2005-2007 Buick Terraza. Always verify your specific year, make, and model before ordering.
Yes, the 05-07 Buick Terraza 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW216 (Part #HBCW216) is designed to fit the 2005-2007 Buick Terraza.
The 05-07 Buick Terraza 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW216 (Part #HBCW216) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Curt 13344 Class II receiver hitch fits 97-07 Chevrolet Venture, 97-05 Oldsmobile Silhouette, 97-05 Pontiac Trans Sport, 05-07 Montana SV6, 08-current Montana SV6 (Canada only), 05-08 Chevrolet Uplander, 05-07 Saturn Relay, and 05-07 Buick Terazza. Fitment varies by wheelbase: short wheelbase models (2004 and older) use different spacer block placement than long wheelbase models. Verify your vehicle's year, model, and wheelbase before purchasing.
The Curt 13344 has a gross load capacity of 6000 lbs trailer weight and 600 lbs tongue weight when used as a weight-carrying hitch. When used as a weight distribution hitch, the capacity is 4000 lbs trailer weight and 400 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these ratings.
Required tools are: ratchet, 6" extension, 3/4" socket, 11/16" socket, 15mm socket, 10mm socket, pliers, drill with 17/32" bit, and torque wrench. A drill is essential because installation requires drilling 1/2" holes in the vehicle frame rails.
Yes. Step 1 of the installation requires lowering the vehicle exhaust by lowering the exhaust hanger on the passenger side. This is necessary to provide clearance for the hitch installation. The exhaust hanger is reattached in Step 7 after the hitch is secured.
If your vehicle has a load leveling compressor, it must be lowered during installation. Step 2 requires lowering the load leveling compressor on the driver's side using one M10 bolt and two M6 nuts. If necessary, the vertical tab on the compressor bracket may need to be trimmed to clear the adjacent M10 bolt. The compressor is reattached in Step 7.
Yes, drilling is required. Step 4 requires drilling 1/2" holes in the vehicle frame rails using the rearmost holes in the hitch side plate as a template. On long wheelbase models, an additional 1/2" hole must be drilled through the forwardmost hole on the passenger side plate. On short wheelbase models, the forwardmost hole aligns with an existing slot in the frame rail and does not require drilling.
Possibly. Step 2 notes that if necessary, the vertical tab on the compressor bracket should be trimmed to clear the adjacent M10 bolt. This is not always required; trim only if the compressor bracket interferes with the M10 bolt during lowering.
Torque all 1/2" hardware to 110 lb-ft. Torque all M10 fasteners to 45 lb-ft. Torque all M6 fasteners to 9 lb-ft. These specifications apply to Step 8 of the installation.
The kit includes: 2 handle nuts (1/2-13 UNC), 2 hex head cap screws (1/2-13 UNC, 1-1/2"), 2 standard washers (1/2"), 1 serrated flange nut (1/2-13 UNC), 4 hex head cap screws (M10x1.5, 45mm), 4 standard washers (3/8"), 1 carriage bolt (1/2-13 UNC, 2"), 1 square hole spacer (.250 x 1.50 x 2.00"), 1 U-shape spacer (.250 x 1.75 x 2.00"), 4 round hole spacers (.250 x 2.00 x 2.00"), 2 round hole spacers (.188 x 1.50 x 2.00"), and 1 fishwire (1/2").
Follow these steps in order: (1) Lower the exhaust hanger on the passenger side. (2) If present, lower the load leveling compressor on the driver's side. (3) Raise the hitch into position and install M10 bolts into existing weldnuts on both sides. (4) Using the rearmost holes as a template, drill 1/2" holes in the frame rails (long wheelbase models require an additional hole on the passenger side). (5) Install the fishwire carriage bolt and spacer blocks on the passenger side through the existing slot. (6) Install the handle nut and hex bolt through the frame rail holes. (7) Reattach the exhaust hanger and load leveling compressor. (8) Torque all fasteners to specification.
On short wheelbase models (2004 and older), place 2 spacer blocks between the frame rail and hitch. On long wheelbase models, place 2 spacer blocks between the hitch and the flange nut. There may be unused spacers after installation is complete. The specific spacer types (square hole, U-shape, or round hole) are determined by the mounting configuration for each wheelbase.
On the passenger side, pass the fishwire carriage bolt and blocks through the existing slot in the frame rail down into the forwardmost hole. Secure using spacer blocks, lock washer, and nuts. The exact configuration depends on wheelbase: short wheelbase models place 2 spacer blocks between the frame rail and hitch, while long wheelbase models place 2 spacer blocks between the hitch and flange nut.
On all-wheel drive models, when reattaching the exhaust hanger in Step 7, it is necessary to pass the exhaust hanger through a 3" long slot in the side plate and use 2 1/4" spacer blocks to reattach the exhaust hanger bracket.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing inspection helps maintain safe operation and prevents loosening of fasteners due to vibration and use.
The manual does not provide the hitch weight specification. Contact Curt Manufacturing or consult the product specification sheet for this information.
Yes, the Curt 13344 fits 97-07 Chevrolet Venture, 97-05 Pontiac Trans Sport, and related minivans (Oldsmobile Silhouette, Montana SV6, Chevrolet Uplander, Saturn Relay, Buick Terazza). Fitment depends on wheelbase: verify your model year and wheelbase before installation.
Yes. Installation requires drilling 1/2" holes in the vehicle frame rails. Long wheelbase models require two holes on the passenger side; short wheelbase models require one hole (the other aligns with an existing slot).
Yes. The exhaust hanger on the passenger side must be lowered. If your vehicle has a load leveling compressor, it must be lowered on the driver's side. Both are reattached after the hitch is secured.
Torque 1/2" hardware to 110 lb-ft, M10 fasteners to 45 lb-ft, and M6 fasteners to 9 lb-ft. Use a torque wrench and verify all fasteners after installation.
Required tools: ratchet, 6" extension, 3/4" socket, 11/16" socket, 15mm socket, 10mm socket, pliers, drill with 17/32" bit, and torque wrench.
Weight-carrying mode: 6000 lbs trailer, 600 lbs tongue weight. Weight distribution mode: 4000 lbs trailer, 400 lbs tongue weight. Do not exceed your vehicle manufacturer's recommended towing capacity.
The kit includes: one 30 amp auto-resetting circuit breaker, two #10 ring terminals, two 3/8" ring terminals, two 1/2" ring terminals, three 12-10 gauge butt connectors, 10 feet of 10 ga black/white duplex wire, 20 feet of 10 ga blue cross-linked wire, and eight 8.5" cable ties.
Yes, but with a critical difference: these vehicles require the stop signal wire to be spliced to the light green wire on the turn signal harness connector under the dash, not to the brake pedal switch. Do NOT connect to the red wire with green stripe, as serious damage may occur. All other vehicles connect to the brake pedal switch instead.
You will need: a test light, wire stripper/cutter, crimp tool, and 3/8" box end wrench. The test light is used to identify the cold (switched) side of the brake pedal switch.
Yes. The manual cautions to disconnect the tow vehicle's negative battery cable before installation. Reconnect it only in the final step after all wiring is complete.
Mount the 30 amp circuit breaker near the tow vehicle's positive battery terminal. This keeps the power wire run as short as possible and protects the circuit.
Use 10 gauge (10 ga) black wire from the duplex wire included in the kit. Strip 3/8" of insulation from each end. Crimp a #10 ring terminal to the end that attaches to the circuit breaker stud labeled 'BAT', and a 3/8" or 1/2" ring terminal (sized to fit your battery terminal) to the end that attaches to the positive battery terminal.
Feed the 10 ga duplex wire from the brake controller in the cockpit through the firewall into the engine compartment toward the battery. Cut to length as needed. At the battery end, crimp a 3/8" or 1/2" ring terminal to the white wire and a #10 ring terminal to the black wire. Attach the black wire to the circuit breaker stud labeled 'AUX' and tighten the nut with a 3/8" box end wrench.
When passing the duplex wire through the firewall into the engine compartment, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to insulate and protect the wire. The same protection applies when passing the blue cross-linked wire through any sheet metal at the rear of the vehicle.
In the cockpit, attach the black duplex wire to the brake controller's battery wire (typically black) and the white duplex wire to the brake controller's ground wire (typically white). Use either one of the supplied yellow butt connectors or solder the leads together and insulate with heat shrink tubing.
Locate the brake pedal switch on the back side of the vehicle's brake pedal. Use a test light or volt meter to identify the 'cold' or switched side—this terminal will only show power when the brake pedal is depressed. Attach the stop signal wire (typically red) from the brake controller to the cold side of the switch using a wire tap.
Locate the semi-circle turn signal harness connector on the steering column under the dash. It has two rows of wires: a row of four and a row of seven. Attach the stop signal wire (typically red) from the brake controller to the light green wire using a wire tap. Do NOT connect to the red wire with green stripe, as serious damage may occur.
Feed the 10 ga blue cross-linked wire from the brake controller to the trailer connector at the rear of the vehicle, taking up any slack in the wire. When passing through any sheet metal, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to protect the wire.
Attach the blue cross-linked wire to the brake controller's electric brake wire (typically blue) using one of the supplied yellow butt connectors or by soldering and insulating with heat shrink tubing. At the rear of the vehicle, trim any loose blue wire and attach it to the trailer connector's electric brake terminal. Refer to the trailer connector's wiring diagram for the correct terminal location.
Secure any loose wires with the cable ties provided. Connect the black power wire from the circuit breaker to the positive side of the battery. Connect the white ground wire from the brake controller to the negative side of the battery. Finally, reconnect the tow vehicle's negative battery cable to the battery.
The circuit breaker is 30 amps and auto-resetting. It must be mounted near the positive battery terminal and connected directly to the positive battery terminal via the included black 10 gauge wire.
Use a 3/8" box end wrench to tighten the nuts on the circuit breaker studs labeled 'BAT' and 'AUX'.
The kit includes 10 feet of 10 gauge black/white duplex wire for the battery and brake controller connections, and 20 feet of 10 gauge blue cross-linked wire for the electric brake signal to the trailer connector.
Black wire connects to the positive battery and circuit breaker. White wire connects to the brake controller ground and negative battery. Red wire is the stop signal wire from the brake controller. Blue wire is the electric brake signal wire. The manual notes these are 'typically' these colours but recommends confirming with your brake controller documentation.
Yes. You can solder the leads together and insulate with heat shrink tubing as an alternative to using the supplied yellow butt connectors. This applies to connections between the duplex wire and the brake controller wires, and between the blue cross-linked wire and the brake controller.
The black power wire must connect directly to the positive battery terminal via the 30 amp circuit breaker. Connecting to the fuse panel or any other accessory wiring may damage vehicle wiring and cause trailer brake failure. The circuit breaker protects the circuit and must be the only protection between the battery and the brake control system.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness. Serious damage may occur. Connect only to the light green wire. Also, do not connect to the brake pedal switch on these vehicles; use the turn signal harness instead.
The kit is universal but requires an existing trailer connector and brake controller. 1989-1991 Ford E & F-Series with ABS use a different stop signal connection (turn signal harness instead of brake pedal switch). Consult your brake controller documentation for compatibility.
No drilling is required. The kit connects to existing components: the battery, brake controller, brake pedal switch (or turn signal harness on 1989-1991 Ford E & F-Series with ABS), and trailer connector.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness—serious damage may occur. Connect to the light green wire instead, and do not use the brake pedal switch.
Connecting to the fuse panel or accessory wiring may damage vehicle wiring and cause trailer brake failure. The 30 amp circuit breaker must be the only protection between the battery and the brake control system.
Yes, the Curt 56077 custom wiring connector is designed for Chevrolet Uplander vans. It is also compatible with Buick Terraza, Pontiac Montana SV6, and Saturn Relay models. All are SUVs, mini and full-sized vans in the S-class category.
Yes, the Curt 56077 is compatible with Pontiac Montana SV6. It fits all four vehicles in the S-class van category: Buick Terraza, Chevrolet Uplander, Pontiac Montana SV6, and Saturn Relay.
Yes, the Curt 56077 custom wiring connector is compatible with Saturn Relay vans. It is designed for all four models in the S-class van category.
The Curt 56077 is a custom wiring connector designed for S-class vans (Buick Terraza, Chevrolet Uplander, Pontiac Montana SV6, and Saturn Relay). It connects to the vehicle's taillight wiring harness to enable trailer lighting functions. The connector is a 4-flat type that routes to the center of the vehicle and out of the trunk for use, and can be rolled up and stored inside the trunk when not in use.
You will need a panel trim removal tool. The manual also recommends having a test light or a properly wired trailer available to test the connector after installation to ensure proper function.
Open the vehicle tailgate, then remove the threshold trim along the rear doors and the interior trim panel on the driver side. Behind this trim panel you will locate the vehicle taillight wiring harness connectors. Use a panel trim removal tool to avoid damage.
Locate the vehicle taillight wiring harness connectors behind the driver side interior trim panel. If the connectors are already connected, separate them carefully without damaging the locking tabs. Insert the custom wiring harness end between the separated connectors, ensuring the connectors are fully inserted with locking tabs in place.
Route the 4-flat connector to the center of the vehicle and out of the trunk when in use. When not in use, roll it up and store it in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
After connecting the harness, reinstall all items you removed during installation. Install the provided 4-flat dust cover to help prevent corrosion. Then test for proper function by using a test light or connecting a properly wired trailer.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire. Check your vehicle owner's manual or contact the vehicle manufacturer for the tow vehicle lamp load rating.
Yes. Before drilling or removing any trim panels, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. When separating the vehicle's taillight wiring harness connectors, take care not to damage the locking tabs.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring connector will function properly.
The Curt 56077 includes the custom wiring harness with a 4-flat connector, a 4-flat dust cover, and cable ties for securing loose wires.
The Curt 56077 is designed for Buick Terraza, Chevrolet Uplander, Pontiac Montana SV6, and Saturn Relay vans. If you own one of these models, it will fit.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause overheating and potential fire.
The manual does not state that professional installation is required. The installation involves removing interior trim panels, connecting the wiring harness to the vehicle's taillight connectors, and routing the 4-flat connector. A panel trim removal tool is needed.
The manual does not specify that drilling is required. It does warn to check for hidden items before drilling, but the installation steps do not describe a drilling procedure.
The 4-way flat electrical adapter converts a vehicle's 4-way flat trailer connector to other trailer connector types (6-way round, 7-way RV blade, or dual 4-way flat). This allows you to tow trailers with different connector styles. Single-output models (57184, 57183, 57185, 57626, 57676) convert to one connector type; dual-output models (57604, 57624, 57672, 57674, 57102) provide two different connector outputs simultaneously.
Yes. Your vehicle must be equipped with a 4-way flat trailer connector. If your vehicle does not have one, you will need to install a custom wiring harness or other 4-way flat trailer connector before installing this adapter.
Both convert a 4-way flat connector to a 7-way RV blade. The difference is that 57185 includes a mounting bracket, while 57184 does not.
Both convert a 4-way flat connector to a 6-way round. The difference is that 57626 includes a mounting bracket, while 57183 does not.
Curt offers three dual-output models that provide both a 4-way flat and a 7-way RV blade output: part numbers 57672, 57674, and 57102. All three include a mounting bracket.
Curt offers two dual-output models that provide both a 4-way flat and a 6-way round output: part numbers 57604 and 57624. Both include a mounting bracket.
You will need: a 1/8" drill bit, drill, Phillips screwdriver, wire stripper, cutting tool, terminal crimpers, and a test light. The manual also lists three self-tapping screws (#10 - 1/2") as required, though these are not included with the product.
No. The three self-tapping screws (#10 - 1/2") used to attach the mounting bracket are not included and must be purchased separately.
Mount the combination harness in a location on the tow vehicle that is within reach of the trailer's wiring harness and near the center of the vehicle. The mounting bracket (if included) should be attached to the vehicle's bumper or other suitable surface.
Yes. You must drill two 1/8" holes: one for the grounding point and one (or more) for the mounting bracket. Before drilling, you must check for brake lines, fuel lines, wiring and other components that may be hidden behind or under the surface to avoid damage.
No. You must never attach the mounting bracket directly to the hitch by cutting, welding or drilling into the hitch. Mount it to the vehicle's bumper or other suitable surface instead.
The adapter uses four wires: Yellow (auxiliary or back-up lights), Blue (electric brakes), Black (positive power with appropriate inline fuse), and White (ground). All wires except black and white must be connected using 12 gauge (minimum) wire and butt connectors to the appropriate vehicle functions.
The white wire is the ground connection. It must be attached with a ring terminal to a 1/8" hole drilled in a suitable grounding point on the vehicle using a #10 - 1/2" self-tapping screw. This ground connection is required for the harness to work properly. The white wire on the vehicle's 4-way flat connector does not support the ground (-) functions of the combination harness.
Yes. The black wire (positive power) must be connected with an appropriate inline fuse. The manual does not specify the fuse amperage rating.
Use 12 gauge (minimum) wire for all connections. The manual specifies this minimum gauge for the remaining wires (yellow, blue, and black) when connecting to appropriate vehicle functions.
Failing to properly ground the product can cause loss of warranty, overheating and potential fire. The white wire must be securely attached to a clean grounding point using a #10 - 1/2" self-tapping screw in a 1/8" hole. The area must be clean of dirt, debris or undercoating.
Before drilling, you must check for brake lines, fuel lines, wiring and any other components that may be hidden behind or under the surface. Drilling into these components can cause damage and personal injury.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding either rating can cause damage or unsafe operation.
Confirm proper function with a test light or by using a properly functioning trailer. This verifies that all connections are working correctly before towing.
Secure any loose wires using cable ties or equivalent product to prevent them from moving, catching on components, or becoming damaged.
Your vehicle must have a 4-way flat trailer connector. If it does not, you will need to install a custom wiring harness or other 4-way flat connector first. Check the part number table to confirm the adapter converts to the connector type you need.
You must purchase three #10 - 1/2" self-tapping screws for the mounting bracket. You will also need an appropriate inline fuse for the black (positive power) wire; the manual does not specify the amperage.
Yes, you must drill two 1/8" holes: one for grounding and one for the mounting bracket. Before drilling, check for brake lines, fuel lines and wiring behind the surface. Never drill into the hitch.
Yellow = auxiliary/back-up lights; Blue = electric brakes; Black = positive power (needs inline fuse); White = ground (must be properly grounded or warranty is void and fire risk exists). Use 12 gauge minimum wire and butt connectors.
Proper grounding of the white wire is critical. Failing to ground it properly can cause loss of warranty, overheating and fire. The grounding point must be clean of dirt, debris and undercoating.
Test with a test light or by using a properly functioning trailer to confirm all connections work. Secure loose wires with cable ties.
