The unit has a switch of its own.... out @100psi... in@70psi and a thermal over load cut...... the plan is to plumb in to a reservoir to operate air lockers and other goodies... I haven't had time to mess with it much yet....
This thing is designed to be mounted on top of the frame rails on a mounting pedestal.... I wanted it low between the frame rails on a 40, but the cable spool is off set to the drivers side and it wouldn't be centered... plus its so wide I would have to do some trimming in the rail area.... the next concern is obstruction of air flow to the radiator,, its like 14" tall....... the base plate mounting hole dimensions are 10.0" X 4.5"......more to come as time permits..
