In a previous thread, I need help to solve a problem with my trailer wiring. I am looking for the wiring diagram for the truck side of the 7 pin connector. I have one relay that is not working and I know the relay is good, so I am in hopes there is a bad fuse somewhere. A wiring diagram of that portion of the truck will be greatly appreciated.

 

Can someone please help? I have searched autozone but they do not have it.
