Yes, the 99-09 Pontiac Montana Excluding SV6 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW2130 (Part #HBCW2130) is designed to fit the 1999-2009 Pontiac Montana.
The 99-09 Pontiac Montana Excluding SV6 2 CURT Trailer Hitch + Assure Proportional Brake Controller Kit HBCW2130 (Part #HBCW2130) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Curt part number 13336 is designed for 05-07 Buick Terraza, 05-08 Chevrolet Uplander, 09-current Chevrolet Uplander, 05-07 Pontiac Montana SV6, 08-current Pontiac Montana SV6 (Canada only), and 05-07 Saturn Relay. Verify your vehicle year, make, and model against this list before purchasing.
The manual lists gross load capacity specifications for both weight-carrying and weight-distribution use, but the specific capacity values are not filled in on this copy of the manual. Contact Curt Manufacturing directly with your part number (13336 or 78227) to obtain the exact towing and tongue weight capacities. Always verify that the hitch capacity does not exceed your vehicle manufacturer's recommended towing capacity.
The kit includes: 2× 7/16" fishwire, 6× M10×1.5 hex head cap screws (HHCS) grade 10.9, 6× 3/8" conical washers, 2× 7/16"-14 UNC carriage bolts grade 8, 4× 7/16"-14 UNC serrated flange nuts grade 8, 2× hex tap bolts, and 2× 0.250" × 1.00" × 2.50" square hole spacers.
No drilling is required on current model vehicles. However, the manual notes that frame drilling may be required on older Montana vans. If you own an older Montana van, contact Curt Manufacturing or a professional installer to determine whether drilling is necessary for your specific vehicle.
You must remove: (1) the rubber exhaust hanger and lower exhaust hanger bracket on the passenger side, (2) the fascia support bar from the frame rails on both driver and passenger sides, and (3) the compressor from the driver side if equipped. All of these components are reused or reattached after the hitch is installed.
1. Remove rubber exhaust hanger and lower exhaust hanger bracket on passenger side. 2. Remove fascia support bar from frame rails on both sides. 3. Disconnect and lower compressor from driver side if equipped. 4. Fishwire 7/16" carriage bolts and spacers through access slots in frame rails, leaving them inside the frame rail. 5. Lift hitch into position and secure with M10 bolts and 3/8" conical washers, finger tighten. Finish fishwiring carriage bolts and spacers into position and secure with flange nuts. 6. Reattach exhaust hanger bracket (some models require it to pass through hitch side plate and attach to hitch mounting tab using 7/16" bolts and flange nuts). 7. Reattach fascia support brackets and compressor (trim compressor bracket before reinstalling). 8. Torque all fasteners to specification.
Fishwiring is the process of threading the 7/16" carriage bolts and spacers through the access slots in the frame rails before the hitch is lifted into position. The bolts and spacers are left inside the frame rail until the hitch is raised and secured. Do not remove the fishwire from the carriage bolt until the hitch is raised into position and secured.
Torque all 7/16" fasteners to 70 ft-lb and all 10mm (M10) fasteners to 45 ft-lb. This applies to the carriage bolts, flange nuts, and M10 hex head cap screws.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing inspection helps maintain the integrity and safety of the installation.
Do not exceed your vehicle manufacturer's recommended towing capacity. The hitch has its own capacity ratings, but your vehicle's towing limit is the controlling factor. Always follow the lower of the two limits.
Yes. The installation instructions include a step to disconnect and lower the compressor from the driver side if equipped. After the hitch is installed, the compressor is reattached. The manual notes that the compressor bracket may need to be trimmed before reinstalling on the vehicle.
Yes, the Curt 13336 is designed for 09-current Chevrolet Uplander models, which includes 2010.
No drilling is required on current models. Frame drilling may be required on older Montana vans; contact the manufacturer if you own an older model.
The manual does not specify which tools are required. Contact Curt Manufacturing or consult a professional installer for a complete tool list.
Torque 7/16" fasteners to 70 ft-lb and 10mm fasteners to 45 ft-lb.
Remove the rubber exhaust hanger, lower exhaust hanger bracket, fascia support bar, and compressor (if equipped). All are reattached after installation.
The manual does not provide the specific capacity values. Contact Curt Manufacturing with your part number for exact towing and tongue weight limits, and verify they do not exceed your vehicle manufacturer's recommended capacity.
Periodically check that all fasteners are tight and all structural components are sound.
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 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.
