The easiest and best thing to do is to buy the harness that just fits into the factory wiring. It's avaible at most parts stores and it isn't expensive. That way you don't have to cut and splice.
you can buy a wireing harness that just plugs into your existing wires at a parts store, you do not have to cut any wires! just unplug back by your bumper and plug in the new plug. that's it.
Plug in the trailer harness into the 7 pin hookup next to the receive hitch if you have a stock towing package.
Not all trucks are built with a trailer harness plug. If you can not find one, then your truck does not have one and you need to install one.
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".
Yes. Check the fuse/relay center under the hood.
