hey nice but how did you wired it up did you just do a new dadicated circuit or .. i already got a/c so i was thinking using the a/c circuit since it already have a relay and fuses
any idea??

thanks

You could use the factory wiring, but you'll have to short the pressure switch that's used to prevent the compressor from starting if there's low pressure. It will also only work with the blower motor on, and will come on with defrost.

I'd use the button, but run my own circuit. A/C now stands for Air Compressor.

I would definetily use a blow off for safety, I think PA has them. Also for a disconnect cover I use a cap meant for hydraulic lines, also from PA.

PA does have them, but they're not the nice small ones you find on "portable" compressors. I've sold the truck, but the owner put a 150psi burst disc on it... no idea where he found it.

The hydraulic cover is a good idea though! I'll nab one of those for my next one.
