I've had the opportunity to refurbish a couple of 69 headlight harnesses, and I ran across something unusual and is not documented in the various schematics. There is a female bullet plug coming off of the VR with green/red wire (904); this plug is oversized much like the PRDNL plug at the firewall. The VR has a second female bullet plug with yellow wire for the radio suppression capacitor. Does anyone know what the other female bullet plug (green/red) may be used for?
