brake controller install in chevy express van chassis
Can anybody give me info on installing a brake controller on a 2005 Fleetwood Tioga 22b with a chevy express van chassis. It has the 6.0 vortek motor. It is prewired with a 7 pin connector in back but for the life of me I can't figure out which wires to hook the brake controller into under the dash. According to the chassis manaul if it has the optional trailer plug wiring I should be looking for a harness in the front with a black,dark blue, light blue and red wire with a white strip on it under the left side of the dash instrument panel. I can find no such combination. I am wondering if maybe fleetwood installed the back connector instead of chevy and that the places to hook in are different that what the chassis instructions say. From the research I have done the Express van chassis didn't come with a place to just plug into in front like the fords do. If anybody has done this I would appreciate any help. Thanks, Jeff.
