Your best bet is to purchase an original harness from a Jeep Dealership. The cost is $91.00 and a step by step booklet with all the components including special wire ties are included. I didn't listen when I was told to purchase an original and purchased an aftermarket harness. This only lasted two weeks. The original fits perfect. Even the module is factory insulated.
Trailer wiring harness part #118382 - any local Auto Parts Store should care this.
The trailer harness plug should be located behind the rear license plate holder. Some 1997 Chevrolet Tahoe's were not equipped with the trailer harness plug.
you do not need the extra 7 pin if your not running electri brakes
Auto parts stores can sell you a trailer harness that plugs in between your existing truck harness. The electrical connection used is usually located behind the rear bumper on the inside of the left frame. Directions will come with the trailer harness kit.
There are about 5 fuses for the trailer harness, Trailer Back up,Trailer left turn, Trailer right turn, Trailer Brake, and Trailer hazards. They are located in the underhood fuse box on the Drivers side of your motor. On my 2003 Silverado, the Trailer left/stop and Trailer right/stop fuses are located in the fuse panel just inside the driver's side door. (Not sure about the trailer brake or hazard fuses.....I wasn't having problems with those :). There is one additional fuse for the trailer harness. The 15A fuse for the trailer running lights is located in the fuse panel under the hood, next to the battery. The fuse is labeled "Trailer Park".
If the 2004 GMC Envoy came with a tow package, then there should be a trailer brake controller harness. It would be located up under the dash near the brake pedal.
Buy a kit at Wal-Mart, auto parts or U-Haul comes with instructions
2006 Dodge Dakota - Where do i find the trailer wiring harness
Do not purchase a universal harness. Purchase an OEM type trailer harness for your ride and it will fit perfectly and be basically a plug in type. It will cost more but is worth it. The instructions that come with it will describe in detail the installation. The 2002 - 2005's are the same. hitches4less sells the OEM wiring harness. It is basically a plug-and-play installation. Unlike other harnesses, however, the liberty also has a ground wire and a "hot" wire from the converter. After plugging the harness into the exiting plugs, you have to ground the converter, and then run a hot wire (with an inline fuse) to the battery. This hot wire, as per mfgr. provide power to the trailer lights.
Yes, on a 2001 Tacoma it was a blown 5 amp fuse in the separate harness dedicated to the trailer lights. I did not realize Toyota Tacoma's came with a separate harness and fuse block just for the trailer lights/harness (this is separate from the under dash (#1) and under hood (#2). On a 2001 Tacoma , it located underneath the driver's side rear jump seat next to the factory tire jack.
Fuse is located on the positive battery terminal labelled F/L 30A
You can find a trailer wiring harness for a Chevrolet in a Haynes repair manual. The manuals are available at most auto parts stores.
