this would essentially make that 9/10v stay only on the G wire and not impact the brake light wire. this way the faint brake light illumination would stop but when I press the brake pedal and it sends 12v to the brake lights it would also send 12v to the G wire back to the cruise module.

so that I think would solve the brake light issue but still doesn't help figure out why the cruise control wont work
I checked my cars today and the brake lights do not glow at all, but yet I still get that 9v on that wire. Its really strange. After all the tests you have done and seeing that it appears to be wired right, I think I wuld try another module. If you dont have a junk yard near you I can probably find one but not sure what it would cost to ship it.
