I have an 05 f350drw and i am also having problems with the tbc. I won't even have a trailer hooked up and the display center beeps and tells me i have a trailer problem. only, theres no trailer. I haven't had problems while pulling any of the trailers. 5 different trailers. no problems. Ford is clueless and my trailer guy isn't quite familair with these yet to diagnose problem. I also have no idea where the wires to connect to my upfitter switches are, neither does the ford dealership. Any help?

 

Acording to my 06 owners manual the upfitter wires terminate behind the passenger side kick panel. I have not looked but will be useing them soon so I hope they are there.

 

Do a search on this and you'll find descriptions of where the wires are and pictures of where they were found by other posters...

"Update" After receiving my Upfitter Switch kit I have found that these wires terminate behind the fuse panel on the drivers side just where the harness plugs into it. This is the install kit and could be different from an original install but this is where mine are terminating at.

 

2012 f-250 I'm having a problem when I slide my hitch for my fifth wheel brake controller works fine but if I do it again to see if it locked I have no brake on my controller any help would be appreciated
