what are you concluding here?
Wire it in with the relay in such a way that it will be easy to bypass the relay if it switches the other way. Try it and see what happens?
What do you mean if it switches the other way? What other way? Are you still supporting the 0v, 12v on brake pressed theory, or is that out at the window??
The relay is wired in such a way that I get 12v with key on, and 0v when brake is pressed, which I though was the correct way on gen 3 ls until I read from a post above that gm wants the opposite (0v, 12v brake press) of that. Is that still valid, or is Alldata showing something else?
I can understand wiring it without the relay if I had cruise control, I just don't understand the 0v, 12v brake pressed on a tcc.
I hope others can tell us how they have theirs wired.
