scottwetzel Posted October 31, 2016 Share Posted October 31, 2016 Alright I'm finishing up my 1986 Superliner build and the red wire that goes to the brake lamps for the trailer in the trailer connector is always hot. The tractor brake lamps work normal. I know a easy fix would be jump the wire from the tractor brake lamps to the trailer red wire but I kinda want to fix it the correct way. Any help would be great.

scottwetzel Posted October 31, 2016 Author Share Posted October 31, 2016 And I have not hooked the airlines up to a trailer yet. When I'm doing this the trailer brake valve is out. I did push it in and the air was leaking down checked the junction block on the fire wall and it's still hot. Strange. Quote Link to comment Share on other sites More sharing options...
