I bought a used jeep 2005 wrangler unlimited that has a trailer hitch that seems to be a mopar product. the hitch wiring harness was never installed. I have the wiring harness but no diagram or instruction. Can anyone help?

Jeep Wrangler 07 15 Tow Hitch and Trailer Wiring Install NeWere4x4

is the trailer attached to the ball on the van?? could be a ground problem,,run a jumper from hitch to trailer see if that works,,

I tow my 2005 Jeep Wrangler behind my motor home. I installed a Jeep trailer towing wiring kit to the rear lights. the bought a long trailer wiring kit and ran it from the front of the Jeep to the Jeep tralier wire plug. Pluged it in and pluged the other end into the motor home trailer light recptacle. I used only four wires plus ground. There is probably a way you could tap into the wiring harnes under the hood but not having a wiring diagram this is the best I could come up with and all lights do work. You can buy a test plug with led lights that plugs in both male and female, real handy for checking connections.

Any luck with plow wiring this season, or do you still have issue. Let me know resolution, since I have similar problem. Thanks.

I advice you don’t cut into the wiring harness but get the proper kit that is plug and play.

That's not a remote starter on your key chain, it's a keyless entry for an alarm system.

I had the sam problem with my '02 escape when I installed the hitch. I changed the turn signal relay under the dashboard on the drivers side of the dash with one from an escape that had a tow package(one was blue and the other was yellow...). worked fine for me after that. Don't know if it changed later...

I just bought a wiring adapter from mopar for this. you take off the rear tail light on the drivers side and unplug it from its harness. the mopar wiring kit i bought plugs into the wiring from the car and has two outputs on it. one for the tail light and a longer one that will run down thru the frame and come out under the bottom by the bumper in just the right spot. i has the plastic clips in just the right spots for snapping into the frame underneath too. took me 5 min to install no splicing required. i got mine off ebay for about $20. super easy! good luck!
