Just finished my install this past weekend.
I ran 6 Gauge to a 100 amp bus in the bed compartment. then wired the 444C viair compressor in the other bed compartment. Ran the air line from the rear of the truck up to the tank behind the front bumper. I have a small leak… I sprayed the lines with Snoop and it is one of the push to connects. I am going to cut a piece or put in a new line and see if the leak stops.
I have the set-up all thru the ignition. so the horns nor the dump will work without the key turned to the ON position.
The compressor is on a factory push switch on the dash, so I have the ability to toggle it on/off but the key must be in the ON position for it to operate.
My compressor is shutting off at 140 lbs and coming on at 115 lbs. Is there an adjustment to get it up to 145 lbs?
More pics to follow when I clean up the rest of my wiring.

The shutoff and start pressure is controlled by your pressure switch. If it isn’t adjustable then get one that is or one with a higher shutoff.
