My build consisted of new barrier hoses, underbelly and quaterpanel condesners, pro cooler, sanden 508 compresser. Right now I just have to flush, hook up the electrical and charge.

I have 2 more questions. #1 I have a spal fan on the quarter panel condenser and wired it up through a relay set up shown on the board here. I am not sure how to wire up the high/low pressure switch though?? It has 4 wires coming out of it and no instructions...anyone know where they should go?


#2 I did not put in a new expansion valve. If I want to run r134a do I need a new valve? Are these universal?

THANKS
