Why so snarky? There are a number of different ways to approach this mod. There is no one way. I’m just sharing what worked for me. My single works perfect off aux four. I used the ACM bracket in the wheel well with the remote chuck. I slipped a short section of bicycle inner tube over the chuck to keep it clean of mud. I might sew the open end of it up to close it off.You powered your compressor from AUX4? Good luck. Aux 1 or 2 will work for a single, but not 3 or 4. And for a winch to work from Aux switches it has to be toy car winch , unless you meant control the relay for the winch. And if latter is true, than why do you need 40 amp switch to control a relay?
My ARB single HO compressor has a relay for the wiring harness to connect to. Wiring harness rus to the aux pig-tails near the battery.
As far as the winch—I have not purchased one yet. Looking at the Warn Zeon 10S. But not in a hurry. I’ll research it before I install it. None of this is rocket science. Just take some time, read up, follow the directions. Easy day.
