AC switch

You have the wrong switch. You need the 3 wire swicth.

Thanks. I was afraid of that.

I spoke with the guys at PI. The two wire switch will work. One of the leads is hot, probably the red wire and the other two go to the fan on the condensor and the compressor. I just need to combine the 2 for the fan and compressor.

Vince,

The compressor cycles as the temp of the air exiting the evaporator increases & decreases. The condenser fan on early cars turned off & on with the cycling of the compressor, on later cars the fan ran full time, it didn't cycle. This was one of Ford's "improvements".

I don't know at which point in the production of the Pantera that change was made, but I believe it was one of the earlier revisions. Obviously by combining wires the condenser fan will now cycle with the compressor, which may be altering the fuctionality of your car, going backwards from Ford's improvement.

Regardless of that issue, you now have twice the current flowing through the one contact. Safe to say, pulling 2 relays shouldn't be a problem, but directly sourcing 2 loads WOULD be a problem. So, the second question is, does your car have the relays for the compressor clutch & condenser fan?

Jerry probably already has these issues under consideration & I'm raising the red flag for nothing, if so I apologize.
