I have an 02 Trac (09-01) and have turn and brake lights on the trailer, but no trailer running lights. I have checked the fuse and relay. I have power at the relay, and coming out of the relay, but at the plug under the cab where the harness leaves the interior and enters the frame, I have no power at the plug (brn/w) I have applied power to the frame side of the plug and get the lights to light on the trailer. So I'm losing connection between the trailer tow relay (auxillary box 2 under the dash) and the frame plug under the cab. Is there another plug between the relay and the frame plug before I go ripping the interior out finding the open circuit? Keep in mind I am not blowing any fuses, so its not a short. Thanks for the help...
