Hello all,

I've a 1982 f100 with a 302 in it. I've already converted to the sanden style compressor from the york dealer install.

I'm now moving to a serpentine system from a 1994 F150 and I'm trying to figure how to wire in the 1994 compressor to the 1982 system. Can I just continue to use the external pressure switch and find the one HOT wire the compressor needs or should I just use the compressor's internal wiring and figure out how it works?

Please help and thanks in advance!
