The TAC ties into the cold side of the brake light wiring and the PCM side will be the other set that needs ignition power and will send power to the PCM when the brakes are not applied.

I have the ECM yellow wire going to the cold side of the brake light switch, is this backwards ...and it's supposed to be to orange brake switch wire12v.....and the green power wire from cruise switch goes to the cold side of the brake light switch....Sorry I'm electronicly challenged.
Need some more info. Do you have the pigtail that the cruise switch plugs into? Because the colors are different on it than what's actually in the lever it's self. Also, is this a DBW set up?
