Can someone tell me what each of the 6 colored wires at the brake light switch go to? The repro workshop manual I bought is missing
the wiring diagram section at the end. Mainly need to know which is + alive when the brake pedal is pressed and which is ground. I think
orange is the + and blue is the ground but need to be sure.

Go to Auto Zone's web site. They have a lot of diagrams where you might find your answer.
