CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Mitsubishi Endeavor (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

Open the rear hatch and remove vehicle floor coverings and the spare tire storage cover. Remove the storage compartment cover on the driver's side by removing two cargo anchor brackets using a 10 mm socket.
A 10 mm socket is required to remove the two cargo anchor brackets from the driver's side storage compartment cover. Silicone sealant (not provided) is also needed to seal the grommet after routing the 4-flat connector.
Locate the vehicle's factory tow harness under the storage compartment. Insert the converter harness into the vehicle's tow harness, ensuring the connectors are fully inserted with locking tabs in place.
Adhere the black converter box to the frame of the car using the double-sided tape provided in the kit.
Route the 4-flat through the grommet in the rear center of the spare tire storage area. Outside the vehicle, route the 4-flat to the center of the bumper and secure it in a convenient out-of-the-way location using the cable ties provided.
No drilling is required. The 4-flat connector is routed through an existing grommet in the rear center of the spare tire storage area. The grommet must be slit and sealed with silicone to create a moisture-tight seal.
Before slitting the grommet, verify that miscellaneous items hidden behind or under any surface are not present to avoid damage and/or personal injury.
Use silicone sealant to seal the grommet after routing the 4-flat connector through it. This creates a moisture-tight seal. The manual does not specify a particular brand or type of silicone.
