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 Jeep Grand Cherokee (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.

You will need a screwdriver to remove the plastic fasteners securing the taillight housings. The manual also references a 3/32" drill bit if you need to drill a grounding hole, and provides an eyelet and screw for grounding. Cable ties are included to secure loose wires.
Open the rear hatch. Using a screwdriver, remove the two plastic fasteners securing each taillight housing. Carefully pull out on the taillights, taking care not to damage the alignment tabs (marked as B in the manual).
The T-Connector is a wiring adapter that splits into two ends: one with a yellow wire and one with a green wire. On the driver's side, insert the T-Connector end with the yellow wire between the separated factory taillight connectors, ensuring the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the T-Connector end with the green wire.
Route the T-Connector end with the green wire down through the opening under the taillight assembly on the driver's side. Then route it under the vehicle along the backside of the bumper to the passenger side, and up to the passenger side taillight housing through the opening on the passenger side. Insert it between the separated connectors as described in Step 2.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no suitable point exists, drill a 3/32" hole and secure the white wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
Route the 4-flat connector to the center of the vehicle and secure it in a convenient, out-of-the-way location. Secure any loose wires with the cable ties provided in the kit.
Drilling is not always required. The manual instructs you to locate an existing screw with nut in the vehicle's frame for grounding. Only if no suitable grounding point exists should you drill a 3/32" hole for the white wire eyelet and screw. Before drilling, verify that no miscellaneous items are hidden behind or under the surface.
If you need to drill a grounding hole, the specification is 3/32" diameter. An eyelet and screw are provided in the kit to secure the white wire in this hole.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface. This precaution avoids damage to hidden components and personal injury.
When removing the taillight housings, take care not to damage the alignment tabs. Similarly, when separating the vehicle's taillight wiring harness from the back of the taillight, be careful not to damage the alignment tabs on the connectors.
