One day I was hooked up to a trailer with a reverse solenoid, so while you try to back up you have to energize the fifth wire on the trailer plug so the trailer will roll back. My truck doesn't have that wire so I rigged up a wire off of the running lights, and I guess I blew the fuse in the truck. All of the truck lights work just the trailer running light wire doesn't have power. Where can I find that fuse? Hopefully there is one for that. I tried looking in my owners manual but couldn't find it. Any help would be greatly appreciated!

 

I just looked through your manual - there's a bunch of relays and fuses associated with the trailer circuits - that's what "TT" stands for - trailer towing. I'd start with fuse #67 in the PDB under the hood.

 

thanks, I'll check it out tonight.
