Trailer Lights
 

I own a 98 F150, just wondering if there are 2 fuses on my truck. I have tail lights on my trailer, but no brake lights nor any turn signals? Just being curious if there is a fuse for my tail lights, and a fuse for both turn signals and brake lights for my trailer? When i apply my brakes the brake lights on my trailer doesnt come on neither does my turn signals on my trailer. i just bought the trailer today and its a brand new trailer. They tested the trailer lights, turn signal and brake lights and it all worked, but when they hooked it up to my truck only thing i had was running lights? Can anyone help me with this question. Thanks

I would test at the truck trailer connection 1st and go from there.

Is it a flat 4 connector?

yes, flat 4

Yes there is a separate fuse for the Turn signals / Stop lamps, and Ford did a number in 1998 with the owners manual, by not pointing out the location for some reason.

Under the hood there is a minifuse panel just behind the Battery Junction Box ( engine bay fuse panel )

In this picture, you can see the lid is off of it, with the red base, and the 2 fuses sticking up:

Here is the page from the 1997 owners manual, showing what the 2 fuses are :

There is also a separate panel that the relays are in, which I have yet to find the location information on, that shows where each trail tow relay is at.

I can only pontificate why this info was ommited from the '98 owners manual.

Hope this is the problem, good luck let us know how things turn out.

that solved the problem, thanks for the information
