Hi all, I am cleaning up the wiring on my '73. I have all the schematics and have been through them. I have this 4 wire connector that was behind the dash. It has red, black, black/yellow, and blue/yellow wires. They track towards the rear harness and splice with the back up light (red/blue) wire. I can't figure out what this is for. Any ideas?
