ok i have found some 12v fob style remote on/off switches ... so .... hard mount compressor somewhere in rear. Hard wire to starter battery with appropriate fuses/cables. Plumb airlines to front and rear of car. Fit remote breaker switch in between compressor and it's power supply. Then attach fob key ring to air gun/tyre gauge ... does that sound simples ?? Think I might put in a master switch in case fob or remote breaker fails ... dunno what all this is going to look like in a diagram though ... eeeeekkk
