Ok here is the info I have gotten so far. If you have the offroad lights, GM uses the brake wireing harness for the lights. My airstream dealer then had to hook up the brake controller around the system. He hooked the into the brake signal under the dash. Aperntly this causes the cruise controll to not be able to engage. The only idea they have now is to take the brake signal from the tail lights. Any one else been able to get this to work ?
