Re: 1968 Parking Brake Light Wire Help
Whether power or manual brakes has nothing to do with it. The distribution block under your master cyl has a switch in it - when the pressure between front and rear brakes is unequal, the switch closes, illuminating the BRAKE light on your dash. The tan wire from that switch is connected to the tan wire from your park brake pedal switch at the bulkhead connector behind the fuse box. (It might look like it goes into the fuse panel, but it doesn't -it goes behind it. ) From there it runs to one side of the BRAKE warning bulb on your dash. The tan wire(s) are on the ground side of the circuit as said. The other side of that bulb is fed by "key-on" 12 volts.
"do you know where they connect to the light?" - on a 69, the tan wire goes to the bulb socket. No clue on a 68 - they use that goofy circuit board.
