Not sure on your cruise control situation. Does the speedometer work? Also as for the Jakes some of these engine ecm's are programmed to latch. This means you have to step on the brake pedal before the Jakes will engage. Some trucks come in programmed this way and it drives me nuts. Thought the purpose of a Jake Brake was to help keep you from using the brakes as much?
