i just looked at mine and 1 (purple) is for the torque converter and the other (blue) is for the cruise control. your may be different but thats what i have.

i do know the 1 for the tq converter has to have power when the brake pedal is not pressed. when it is pressed the 12v signal has to stop creating an open circut.

good luck man!

Bob's too quick on the draw!
