Well, this is what I could find (I hate DC's wiring schematics - I am used to GM's). The brake switch should be a flat 6 pin connector. Pin #2 is white with tan tracer and that is for the 3rd brake light. The other pin for the 2 lower stop lamps 'should' be #6 dark green with white tracer. #6 goes to the anti-lock brakes and ECM. I found the 2 circuits that go from the fuse box to the lights, just not the input signal. Test it first with a test light or multimeter while pressing and releasing the brake pedal. Make sure it's supplying 12v only when the pedal is pressed! If it is, then backprobe (not what you think Mikey
) with a fused jumper wire from B+ to pin #6 and see if the lights come on.
