So for safety what you are suggesting is for 12v at a clutch switch going to pin 33 interrupted by pushing in the pedal which shuts off cruise. So before I add that switch I should be able to test for cruise by adding that hot wire directly to pin 33?
When that makes the cruise activate I will gladly wire in that double brake switch on my clutch pedal to activate/deactivate the normally open and normally closed functions for a safe, permanent install.
I will report the outcome.
Thanks again for your expertise.
You cant just put power to that wire and have it work, you would need to momentarily remove the power after starting the truck. The system monitors the brake switch each ignition cycle, and if it doesn't see you press the brake pedal at least once, the cruise is disabled. I have personally tried it on my truck, with a perfectly good working cruise, if I start it and put it in gear without applying the brake, and drive it fast enough for it to set, it doesn't, but one tap of the brake pedal and it works fine again. GM built some failsafe into the system.
