Bought 98 GMC 2500 brake lights did not work.Changed everything.Did not work.What I did know it use to belong to a contractor that used trailers all the time.Then I checked the trailer hitch connections.I saw a white wire grounded to the frame.I checked it with my volt meter.Found out it was hot .Disconnected it.Everthing worked.I found out through a friend of mine that a lot of guys that use trailers do this to disable brake lights on their trucks when using the trailer hitch.My brother in law pointed it out a earlier that it looked odd a white wire was grounded to the frame.Us guys that work on our trucks all the time fix all the big things all the time.Sometimes others see things we don't.
