Wiring a modified air compressor
So I’ve gotten myself down a pretty deep rabbit hole and I’m committed to finishing this project. Long story short i bought a dual head Napa air compressor to fill up my tires and was trying to hard mount it in my truck bed. Some YouTubers led me down another rabbit hole leading me to adding a pressure switch and then to rip out the Chinese motherboard and replace that with a 200a relay. Now here’s the predicament I’m in where the rabbit hole takes a turn. My truck is a f150 raptor that has upfitter switches in the cab that I would like to use. Can someone take a look at this wiring diagram that I’ve drawn to see where I’m messing up? When I get everything hooked up and flip the switch there’s no action. When I bypass the relay it works with the switch off or on. Please help before I pull my hair out
Power and ground from battery is 6ga wire connected to compressor using 125a Anderson connectors.
Power coming from upfitter switch is 30a
Power from battery has a 100a fuse
Compressor is 90a
Relay 200a
