This Switch Pro looks like a great way to go…
To me this wiring looks a little daunting… but this looks like an incredibly clean wiring set up.
What is significant about the AUX switches is, that the truck has to run for the switched items… lights. Air compressor, winch, etc. to work.
You really need an ignition switched operation in order to NOT drain your battery.
So whatever way you chose…. Relays and ignition switched circuits are a must….
Hope this helps😁
