95 ford f250 trailer wiring trouble what does each wire work and what color

use the code that came with the plug. Just sort the car wiring with a volt meter or test light.

Hello, if you only have taillights on the trailer and no side markers, check your bulbs first. The bright side is used for the Brakes and turn signals and the normal filament is used for the running lights.

If you use a test light you can find the pin on the connector which runs the Running lights. Sometimes the wiring harness will pick up the running lights off of the taillight in the bed of the truck. You would look for a wire going up into the taillight housing from the Trailer plug.

If you are the original owner of the truck there was a small package of Relays and wire ends that came in a plastic bag. It could be stored with the jack. This package had wire color information and instructions for Electric brakes. It also color-coded the Trailer plug-in socket as they use the extra pin holes for the Electric brakes. All the wires are discussed.

If an aftermarket unit was wired in the running light, the wires could be any color. The industry tried to put in a standard, but instructions still say if you don't have one color, its another. That is still vague.

then if theres power to harness at back of truck its the harness on trailer or wireing on trailer

Not sure about the trailer connector, but you can download a manual here:

fuses start on page 218

The things you need to check are the wires from the truck and the wireing to the trailer. If you have a 4 pin flat plug the wires are colored white,brown green and yellow.White is ground,brown is the tail light,green is right turn and stop,yellow is left turn and stop.The brake light switch on the brake peddle needs to be adjusted or replaced to cure your other problem.

If It Factory Ford Tow Package And They Have Not Changed Things There Is A Fuse In The Fuse Panel For The Trailer Lights Hope This Helps

yes you can buy the plug at any parts store, wires are all color coded- just clip the wires and crimp the new one on-make sure you use weather tight crimps- putting die-electric grease on the new plug will make it last lot longer
