How do you Install trailer wiring harness on Jeep Grand Cherokee 98?
Go to U-Haul, they do it all the time and have the wiring specks. It's not that expensive.
Cheaper in the long run to rent a TRUCK and not ruin the transmission in the Jeep. They were NEVER intended to tow anything heavy. Bruce
the easiest method is to buy a trailer plug in kit you just plug it into your existing wiring harness,if not most kits come with complete easy to follow instructions telling what wire goes to what light and all you need to do is find the wires on your jeep using a simple test light.
