The experiment was already done via trial and error although obviously I cannot speak as to long term effects. I established that on the brake switch, the four wire connector is for cruise and TCC. By unplugging it, I got the desired result. But that kills cruise. So to me, it stands to reason that two of the four are for cruise and two are for TCC. If only I knew which were which, I suspect I can reconnect two of the four wires there to get cruise back.

Wierdest thing... that no diagrams are out there which identify wires going to the brake switch. I can't find anything and that seems odd. Like anything I attempt... it seems no one has ever run into the same questions or had a similar train of thought.

All I want is that info now. Where the wires go that are in the 4 pin connector at brake switch.

Thanks, Brandon. Any idea where to find the info? Somewhere at some point a schematic must have existed. Camaro (and probably the rest of GM) switches appear to use the same connector configuration. Theres just no clues to find, about what the wires there do.
