Just to put a final on this. I found the cause of my brake lights being on all the time. The two pin connector on the brake light switch at the pedal, while disconnected from the switch, tested hot BOTH pins with the ignition on, when one should not be hot until the depressed brake pedal completes the circuit. I still have failed to find out where that wire goes to that is creating the short. And pulling the 20 amp brake fuse had no effect. I rewired the whole brake light circuit, taped off the old unused wires, and now have normal brake light function. I did put a new 20 amp fuse into the circuit. Thanks again for all the input on this; had the car had stock wiring, this would have been a whole lot easier!
