I hear you Vstech, I love north carolina, we go up to lake Lure every now and then. Have you ever been to the Geneva?

And about the wire:
Could it be that there was originally just a one spade switch on the receiver and that got replaced with a two spade switch for pressure & temp?

The compressor is shot and I'm waiting to get the upper hose rebuilt before i install it. Also, the push button unit was replaced in 2006 with a programa unit and i recently opened up the boards and resoldered a burnt strip to cure my spastic clicking.
