Well, I just found out that my reverse and third brake light are out, and I checked the bulbs, and they are good. DOes anybody have a fuse diagram? I could not locate one in the manual, and am wondering if it is the fuses. Anyone have any other ideas as to what might be the problem? Thanks.

I don't know about the backup lights but I do know that the 3rd brake light is directly controlled by the switch on the pedal. I don't think there is a fuse on it. Do you have a trailer with electric brakes and do the work? The sensing wire for the trailer brakes is on the same circuit as the third brake light.

 

My trailer lights work. Ive never done electrics on a truck before, so I dont know a lot about how it all works. Thanks for yalls help

The trailer lights are on a different circuit still, the sensing wire that actuates the trailer brake controller is on the same circuit as the third brake light.
