I just refurbished a 70 underdash harness, and couldn't find any documentation on two wires.
The first is a large white female bullet plug on the engine side of the firewall. It is tied into the fuse box, but I can't figure out what it connects to on the engine side. Is it for emissions control?
The second wire is a gray wire that ties together a small flat green 3 pin connector and a 2 pin red connector under the dash. Part of these connectors go to the key reminder/door ajar buzzer system.
