Hi Gents,
I'm in the process of reinstalling my ARB air compressor this time without the harness since it melted. It's only for airing up the tyres, and I'm no expert with wiring so hoping someone here can help.This is where I'm at right now, and I'm not sure how the pressure switch needs to connect in this scenario.
Is anyone able to give me some guidance wiring the pressure switch and the console switch into this?

Hi mate, not sure why yoy have drawn a buss bar but assume that is your relay or something. The pressure switch is tapped into the positive side of the supply. I would tap it in between the fuse and the relay so it cuts the relay. It is a gate in the positive only side. Pos in pos out.
In thsi diagram it shows the pressure switch between the switch and the relay mounted on the compressor. The pressure switch can be anywhere in your air lines though. It measures the line pressure.

Red is positive from switch pin 3. DK BLU then goes from pressure switch to relay and is also a positive.
Your positive from battery to fuse, then to Pin 2 on ARB Switch and 30 on your relay.
Something like this you reckon Mudrunner? What do I do with the switch?

As it is drawn there the pressure switch is redundant. The flow of positive must travel through the pressure switch. You drawing it is going through And around it.Quote:

DK BLU goes from Pressure switch too Relay. Switched relay, relay turns on compressor.

RED from switch to Pressure switch
DK BLU from Pressure switch to relay
RED WHT from relay to Compressor
BLK WHT negative battery to compressor

Yeah just a layout for the relay mate. Really appreciate the info, I think I understand it (few beers in for covid relief) will draw it out again with that info and see what ya reckon!
On the relay there will be a number next to each pin. If you draw the relay following the convention in the following link showing which wire goes to which pin it will probably help the confusion.
