Mopar 7-Way Round Trailer Hitch Wiring for 2002-2007 Liberty KJ
Trailer Tow Wiring Harness Kit, with 7-way round connector, plugs directly into the vehicle wiring.
For vehicles without the overhead console, you would also need and additional adapter harness, Item # 82207620AB, to make the wiring work. Unfortunately the 82207620AB harness has been discontinued by Mopar.
