New truck problems
Ok so last night I hooked up to a buddies enclosed trailer. Light all work but my truck says trailer disconnected. Push the brake controller and it shows that the brakes are working while I'm not driving, until I push the lever all the way then it just says trailer disconnected, I checked the battery on the trailer and it shows 12 volts..... Band new truck and I am having a issue

I think there is a fuse and a relay that you have to install, but I don't know where they go. Mine were in the door pocket in a plastic bag, but I didn't install them yet.

The fuse and relay go in the fuse center under the hood but they're for the charge line to the trailer battery and have nothing to do with the brake controller.
Is there another vehicle you can connect the trailer to and see if it's a trailer issue?

Keepin' the lights on!
Start going through the trailer brake wiring. These new trucks are so sensitive that if the trailer's brakes and wiring are not perfect it won't allow the TBC to work. Even if the wiring is good the brake magnets can affect the system from working.
