I have a 2004 GS 36 foot on freightliner chassis with Cat 330 power. Anyone know if there is built-in wiring from the dash to the seven wire plugin receptacle for a brake controller? I can not find any fuse that is labeled for trailer brakes. I have an enclosed trailer with two axle brakes and was hoping that Gulf Stream added wiring along with the seven and also the four pin receptacles at the trailer hitch. There are wires that would reach from California to New York so I hope that one or two of them say "Brake Controller".
July 21, 2014. Everything OK now. I found the bundle of wires labeled Trailer Brake way up under the dash. Now I wish that I had a wiring diagram so I could tell where the wires go. My controller has only four wires and the plug-in has five. Such is life.
What part are trying find? My brake controller wiring was in the left console by the parking brake, others have said it's in the dash, labeled but hard to find. By the hitch I have a 7 pin & flat 4

I was trying to find the brake controller harness. I only have a four pin in the rear. Some people say that if you dig further back you may find the blue wire for the brakes. I figure if I could find brake controller wiring that would give me hope that there was some wiring already ran from the front to the rear.
