HI,

I am trying to get my trailer working. Someone who had my truck before messed up the trailer harness. I think they blew the trailer fuse or relays. I have an 02 f350 and I need the location of the trailer lighting fuses and relays. The chiltons manual said relay box 4. I can't find it..

I have B+ and ground, no trailer brake or right turn signal or parking lights.

Trailer brake works fine at the controller, signal is lost somewhere.

Thanks,
Scott
