on-board air

Has anybody seen a switch that looks like it belongs on an 80 dash, with a graphic for an on-board air system ?

Wife had a trip and needed the compressor but did not take the portable so trying to figure out a relatively simple on board set up. Ideally that could be used if I ever do a rear locker down the road. Mainly thinking the slew arb single but can’t see wiring instructions on their site. Any input...
