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".
check the fuse in the underhood fuse box. There are separate fuses for the trailer turn circuits and tail lights. If the fuse is burnt, replace and reconnect the trailer. If the fuse blows again, check the trailer wiring for a short on the park light wire.
I imagine a 2002 would have similar wiring to a 2000 Explorer which I've just discovered myself has 2 fuses dedicated to the factory installed trailer wiring. Fuse #3 is for the left trailer signals and fuse #7 is for the right. Hope this helps someone to avoid all the hassle I went through to figure this out.
The fuse box is located on the inside of a 2004 F250. The fuse box will be found in the floorwell.
Fuses are designed and intended to protect the wiring from SHORT CIRCUITS and OVERLOADING. When a fuse "blows" instantly upon connecting the trailer wiring to the vehicle wiring connector,suggests a short in the trailer wiring, or one of the light sockets/fixtures. If the fuse did not blow instantly, but over a period of minutes, would be suggestive ofan overload condition. Sinceit blows the tail light fuse, logic suggests the short should be found in the tail light wires or bulb sockets on the trailer. Another possibility, but very remote, is a defect in one or both of the connector plugs. Look for an area ofcut or chaffed insulation onthe trailer tail light wires, where the wire may be "pinched" in a crevicebetween twometal members of the trailer frame, OR where the wire makes a very sharp turn around a metal edge.j3h. you have a short in the tail light wiring of the trailer
Fuse 116 on a 2003 Ford F-250 typically controls the power to the trailer tow relay and various trailer-related functions.
