Thanks Dr Quick,
I'm going through drawings in the manual. I didn't find anything labeled "signal light switch" but I did find a "turn/hazard switch" and outputs A & B from that switch are the Yellow & Dk Green wires that go to the tail lights and on their way to the tail lights they get spliced to feed X & Z wires (same colors) of the tow harness. I haven't found from the drawing exactly where the turn/hazard switch is, maybe under the dash?
I'd sure like to figure this out to do the correct way if possible. If I wire the brake in at the rear then as I understand the brake light will be hot while a blinker is also blinking and I'm guessing we would see the blinker as an intensified pulsing light since the brake light is already on (not lifted)?
