SUBJECT: # 7248: Trailer Wiring Problem - Uhaul did it!

Submitted by Pete F ( from PENNSYLVANIA on 3/8/2002 12:20:00 PM

I have a 98 Jeep Grand CHerokee that I got wired from Uhaul when I had my hitch installed. I Have had this problem for a while but have never taken care of it. Basically all my lights work except for the running lights. U Haul installed the wiring harness with a indicator at the light plug in which tells which light should be on or blinking etc. The indicator for the running lights is always on except when I plug my trailer plug into it it goes off. I know it isn;t the trailer becasue it my trailer works fine on my dads car and my father inlaws car. I have noticed it also when I rent a trailer from Uhaul it does the same thing. If anyone can help that would be much appreciated. I am thinking could it be a bad ground?

    If it was a bad ground on your vehicle, your other lights wouldn't work.

    Find the wire for your running lights, trace it back to where it connects to your Jeep.

    Did they splice or install a "T" ?

    Better yet, take it back to U-haul.

    U-Haul uses a different wiring plan than than standard automotive. When I rented a U-Haul trailer I had to buy a pigtail adaptor to hook up to my exsisting 4 prong plug. If the only time that your lights work correctly is on a U-Haul then they have wired you for their set up indead of the rest of the Industries!

    On my 93 Chevy Silverdo all my lights all work except for when all are on at the same time. The truck lights are fine just the trailer is not working. EX. If the running lights are on and you hit the brakes the lights will completly extingiush. I've tried different grounds for the the trailer but no help. If just running lights are on the blinkers work fine only problem is the brakes. I really appreciate any advise.

    hook it up yourself then you j#$k instead of blaming uhaul and posting it on the web, just because some inexperienced person hooked it up for you! you probably didnt even take it back to them i bet cause i work for uhaul and i know i would of fixed it for you till i found out you posted it on the web.

    Hi "I could care less" and others, I could really use your help. I have a U-haul trailer hitch and I think the wiring was done there too (not original owner) Could you tell me the basic wiring diagram that U-haul uses.The 7-way vehicle end needs replacement, only have loose wires now. Black, Red, Tan, Light Green,Light Blue, Blue/Red, And Brown/Green. Those colors do not correspond to any connector I've seen.(I have a 94 Jeep Cherokee Sport and I like Uhaul!)

    While everyone is on the subject, Ive recently noticed that my running lights dont work at all (only found out when I was pulled over for not having them). All of my other lights work. I drive a Ford Excursion and use a 7-way to 4 prong converter to hook up my boat(s). The running lights dont work on either my SeaRay or my flatbottom trailers. I suspected the adapter so I borrowed my friends U-Haul adapter and got the same thing. Any ideas would help me out tremendously so I dont get pulled over ;) Thanks in advance.

    Mike, check to see that everything is grounded. should be the white wire on your 4-way.make sure there is contact for each light with the trailer, then make sure the trailer is grounded. You could run a connecting wire to each light but you shouldn't need to.Since it's on all of your trailers, Check the ground on the 7-way connector, that's also white. I had to replace my 7-way on the vehicle end because of corrosion. My wiring colors turned out to be Jeep originals and unfortunately diagrams for hitches were not in any manuals. the "wiring guy" at U-haul was very helpful in telling me which colors were "probably" for what. then it was trial and error to verify all hook ups. my running lights didn't work at first because of the grounding issue. Good luck. Paul

    Are there no Auto-Electricians in the US? you all sound like you desperately need to visit one to have all your wiring woes resolved. Spend a couple of dollars and make those trailers Road Worthy!!!
