Hey fellas,

I have a 73 with no A/C. I am trying to id a wire that does not have a home and my wiring diagram does not help. Here is what I have:

Tan wire from the main harness leads to a plastic 2 prong female connector. From this connector is the green wire that goes to temp. guage on the passenger side of engine block.

Any help and wire id resources would be soooooo appreciated.
