I have an 05 Mariner. I installed a hitch and purchased a OEM wiring assembly. Part #6L8Z-13A576-AA. It has a plug on one end and the trailer 4-wire plug on the other. I cannot find a wire with a plug like that anywhere in the rear of the vehicle. Does anyone else have an idea on where it should go? The wiring is only about 2 1/2 ft. long so it can't go far!
