Arb Dual Air Purple wire with Auxbeam switch install

[rezar1]

I am finishing up my Arb dual air compressor and want to connect it to my Auxbeam switch. I wanted to find out what amperage do I need to hook the purple wire to? Auxbeam has 5/10/20/30 amp fuses/connectors. I briefly connected it to the 20A and it worked but wanted to know if I should go higher or can go lower and save 20A for something else?

The purple wire does not provide any power directly to the compressor motors. It is just to switch it on.
Placing it on the lowest switch is fine.

Yeah, the 5a switch will be fine. The arb dual has built in relays so the purple wire is only carrying enough current to switch the relay coils.

The single compressor does not have a relay and requires a 30a circuit.

Thanks!!

The purple wire also powers the cooling fan. No idea how much current the fan draws as compared to the two relays.

I finished the install and connected to the 5a connector. Everything works so far. Will report back if it gives me issues.
