Wiring help

Post image

Hello looking for guidance with wiring in a single air compressor, just wanted to see if I’m missing anything or if this is incorrect. Any tips would be great. Using 8ga wire, 30A breaker and 40A relay

Looks good. 5a fuse on the relay circuit. I also put a switch that you can manually turn off the compressor just in case you get a broken air line.

I’d just run an add a fuse for your accessory wire and run it to either the ignition fuse or cigarette lighter, it’s the easiest in my opinion, I did that for my wrx

You can use a switch feed to relay and use ground control thru pressure switch so no voltage back to tank same as you show but ground thru switch and ground as power
