As I go through the somewhat butchered wiring harness on my new to me '73 2.0L, I've run across a green with white stripe wire which has been lengthened with some butt connectors running along the center of the car. It looks like the wire is connected to the heater control lever. Can someone explain what this does? The only green/white wire I find referenced in the Prospero Garage drawing goes from the heater fan switch to pin 9 regulator plate in the engine compartment. Thx for the help.

When I connected my fan to the connector in the engine bay, it started running regardless of the heater switch position. I ended running a separate wire with a switch that I can turn on when I want, but I've never been comfortable with this arrangement.
It seems that the wire must be grounded somewhere, but I'm wondering if it is just because of the way the heater lever is installed. Is it supposed to have any kind of insulation or a way to prevent the fan being grounded until the lever is all the way up? |
