My 1980 has a single green male spade connector coming from main wire harness. It is located under the shifter console. I have checked both AIM and original shop manual, and it does not show it . It is factory for sure.

 

Hello nickster,

Probably goes to ac system.

Can you show us a picture?

 

Ok, cannot see where i can add that to my post.

 

See if you can open this. If not it's in the sticky section above C3 general posts.

Ok got it.

 

Great.

I'll look on my '81's wiring diagram.

Maybe someone else can chime in?

It doesn't look familiar.

 

Did not see a female connect anywhere when i replaced the bezels and light bulbs.

 

FWIW: your "spare" connector may be for an option not installed on your car.

 

Yes I did think of that, everthing on car works as it should.

 

Does the alarm work correctly? There is a green wire for the alarm key switch and the theft deterrent module. All the other green wires that I see would affect a/c or headlight operation.

This information is from my '81 wiring diagram. I do see the green wire that goes under the dash in the wiring diagram. It is not connected and says it connects to the engine harness. But you knew that.

 

Alarm works as it should, no issues there.

 

Sorry no help here. Just ignore it if everything works fine.

 

If it ain't broke, don't fix it/. Forget you saw it.

Does it have power when the key is on, does it have power all the time.
