Hello evey one. i need help to find the right factory wire harness for my 07 grand cherokee limited 4.7 4x4. i just bought a oem trailer hitch and 7 way round connecter; then was told i need to buy a factory wire harness. ive been to several different sites but there seems to be more than one harness for my vehicle.if some one could point me in the right direction with a site and part# number i would greatly appreciate it. also does any one know of an installation video to help with install?

 

You might run up to your local U-Haul. They do that stuff for a living and can probably tell you exactly what you need. It's likely they'll have what you need and will even wire it up for a few $$'s

 

Yeah man, U-haul! It sounds like you're building your own tow package. I'd advise you to look into an aux trans cooler as well.

 

Thanks for youre help. i bought the harness from mopar one, $77. runs from under hood all the way to rear.requires star scan tool
activation from the dealership. anyone done this before \ know the cost?

 

Oh, that's right! You said you bought a 7-pin coupler. You're going with electric trailer brakes, right?

I once had a 15' travel trailer behind a Chevy 4X4 and the coolest thing I did was install back-up lights on the trailer. It made it SO much easier putting it into a campsite at night!
