If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Dodge Durango and Chrysler Aspen (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

The battery connection must be fuse-protected with a maximum of 10 amps. The harness has the following circuit ratings: Signal Circuits – 3.0 amps per side, and Tail/Running Circuits – 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower, as exceeding the rating can cause loss of warranty, overheating and potential fire.
You will need: Phillips screwdriver, flat blade screwdriver, and panel trim removal tool. A 3/32" drill bit is also required if you need to drill a pilot hole for the ground wire screw.
The manual does not explicitly state whether the battery must be disconnected. However, it does reference routing the black power wire from the vehicle battery as shown on the included CME-PCL-INS sheet. Consult that sheet or contact the manufacturer for battery disconnection requirements.
Open the vehicle tailgate. Remove the two fasteners securing each taillight. Carefully pull the taillight rearward, taking care not to damage the alignment tabs on the back of the housing.
The custom wiring harness end with the yellow wire connects to the driver side (left) taillight. Route this end out from under the vehicle through the body opening to the left taillight housing.
The custom wiring harness end with the green wire connects to the passenger side (right) taillight. Route this end to the passenger side and repeat the connection steps used for the driver side.
Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow for driver side, green for passenger side) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
Drilling may be required for the ground wire installation. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, you will need to drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
Drill a 3/32" pilot hole for the provided ground wire screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Locate a flat spot inside the vehicle near the taillight. Adhere the black converter box using the provided double-sided tape.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness will function properly.
The battery connection must be fuse-protected with a maximum of 10 amps. Exceeding this rating can cause loss of warranty, overheating and potential fire.
