Seeking guidance regarding A/C pressure switch wiring.

otisMember

I have started my A/C upgrade with a new expansion valve, line, dryer and compressor. My compressor is a Sanden SD5S with flare fittings made up by Larry Stock. I need a little guidance with the wiring. It has a pressure switch added on the back side of the compressor. Where do I run the new pressure switch wires to?

The car is a 74 and some of my wiring has been messed with. My old compressor was a Sankyo SD510 (not the original York) it had one red wire and this new one has one black with a bullet end on it.

Any advice is appreciated, thanks.
