The 04 - 08 Chrysler Pacifica Excluding hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK642 (Part #7WK642) fits the following vehicles: 2004-2008 Chrysler Pacifica. Always verify your specific year, make, and model before ordering.
The 04 - 08 Chrysler Pacifica Excluding hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK642 (Part #7WK642) fits 2004-2008 Chrysler Pacifica models. The 2008 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the 04 - 08 Chrysler Pacifica Excluding hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK642 (Part #7WK642) is designed to fit the 2004-2008 Chrysler Pacifica.
The 04 - 08 Chrysler Pacifica Excluding hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK642 (Part #7WK642) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
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.
The Curt 55530 is designed for Chrysler Pacifica models with a factory 7-way connector. The manual specifically covers 2004-2006 Pacifica models. If your vehicle has a factory 7-way connector, it should be compatible. Check your vehicle's owner's manual or contact the vehicle manufacturer to confirm your model has the factory 7-way connector before purchasing.
A factory 7-way connector is a wiring connector built into your vehicle's taillight system by the manufacturer. The manual does not provide visual identification details. Check your vehicle's owner's manual or contact your Chrysler dealer to confirm whether your specific model year and trim level includes this factory connector.
The kit includes: a custom wiring harness with yellow and green wire ends, a 2-pin connector, a black converter box, a 4-flat connector, a 4-flat dust cover, provided sealant, cable ties, and (for 2004-2006 Pacifica models) a 20-amp fuse. The manual does not specify quantities of cable ties or other consumables.
You will need: Phillips screwdriver, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, cutting tool (utility knife), and a 10 mm socket or wrench. The manual also requires a double-sided tape applicator (or hands) and a utility knife for making the grommet slit.
Yes. Step 1 requires opening the tailgate and removing two 10 mm bolts securing each taillight assembly. You must pull out the taillight assemblies carefully to avoid damaging the alignment tabs. This provides access to the vehicle's taillight wiring harness connectors needed in Step 2.
1. Route the yellow wire end behind the seat belt bracket and out through the driver-side grommet, then insert it between the separated driver-side taillight connectors. 2. Route the green wire end from under the interior trim panel, under the removed cargo tray, and under the passenger-side trim panel, then out through the passenger-side grommet and insert it between the separated passenger-side taillight connectors. This routing keeps the harness hidden and protected.
The black converter box is part of the wiring harness system and converts the vehicle's taillight signals for trailer use. Mount it on a flat spot inside the vehicle near the taillight using the provided double-sided tape. The manual does not specify exact location requirements beyond 'flat spot' and 'near the taillight.'
No drilling is required. However, you must make a small slit in the oval grommet using a utility knife from the top to the middle on both sides of the vehicle (Step 4). This slit allows the wiring harness to pass through. After installation, the slit must be sealed with the provided sealant.
Signal circuits are rated for 3.0 amps per side. Tail and running circuits are rated for 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
A 20-amp fuse must be inserted into position 10 in the vehicle fuse box, labeled 'TRAILER / TOW'. The fuse box is located in the engine compartment on the driver side near the battery. This step applies only to 2004-2006 Pacifica models; other model years may have different requirements.
The manual identifies the harness as having a yellow wire end and a green wire end, but does not specify which wire corresponds to which circuit function (signal, tail, running, or ground). Consult the wiring diagram on the harness packaging or contact Curt Manufacturing for wire function details.
Do not exceed the product rating (signal circuits 3.0 amps per side, tail/running circuits 6.0 amps total) or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire. The battery connection must be fuse-protected with a 10-amp maximum fuse.
Test for proper function by using a test light or by connecting a properly wired trailer. The manual does not provide detailed test procedures. All installation steps must be followed to ensure the harness functions properly before testing.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. Install the provided 4-flat dust cover to help prevent corrosion. Secure any loose wires with the provided cable ties.
Yes, but only temporarily. Behind the interior trim panel on the driver side, remove the seat belt bracket by removing two bolts holding it in place (Step 4). This provides access to route the yellow wire behind the bracket and out through the grommet. Reinstall the seat belt bracket after routing the harness.
The provided sealant is used to seal the small slit made in the oval grommet and around all wires passing through the grommet (Step 7). This prevents water and debris from entering the vehicle through the grommet opening.
Yes. Step 3 requires folding the rear seats down and removing the rear cargo tray cover. Remove the cargo tray by removing four 10 mm bolts. This provides access to route the green wire under the cargo tray area to the passenger side.
Yes. Step 3 requires removing the scuff panel by pulling out on the bottom and then up. Take care not to damage the alignment tabs on the back. This provides access to the interior trim panels and grommet areas needed for routing the wiring harness.
The Curt 55530 is designed for Chrysler Pacifica models with a factory 7-way connector. Confirm your vehicle has this factory connector by checking your owner's manual or contacting your Chrysler dealer before purchasing.
You will need: Phillips screwdriver, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, cutting tool (utility knife), and a 10 mm socket or wrench.
No drilling is required. You must make a small slit in the oval grommet using a utility knife, which is then sealed with provided sealant.
A 20-amp fuse must be installed in position 10 (labeled 'TRAILER / TOW') in the engine compartment fuse box on the driver side near the battery. This applies only to 2004-2006 models.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
Signal circuits: 3.0 amps per side. Tail and running circuits: 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Test for proper function using a test light or by connecting a properly wired trailer. All installation steps must be followed before testing.
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.
