Rally dash redo
My 67: two purple wires from the trans.
One wire goes to the reverse lights, which are grounded to the body.
The other wire goes to the wiper switch, that's right, gets power from the wiper switch. At the bulkhead this purple wire is connected to the white wire that goes to the wiper switch.
My understanding is the switch has an internal circuit breaker, not sure if that is for the wipers or the reverse lights, or both. I do know that sometimes when my reverse lights wouldn't work, if I turned on the wipers, once they started going the lights came on.
Have since taken the switch apart and cleaned it, grounded the reverse lights to a ground hub that returns to the battery. Didn't help with the issue.
Since I replaced the fusebox with one with modern fuses, I plan on taking power from somewhere else so the wiper switch will no longer be involved in the reverse lights.
Iirc, the only thing wrong with the diagram I have is the wiper only had 3 wires, not 4, and the colors are incorrect for 67. The wiper wires/colors are correct for a 68, or could just be for a variable speed and I have the two speed.
