no, I couldnt figure out what the little red wire went to. I only had 1 main wire going to the battery, understood the ground, and the wire going to the compressor. I need another wire going to a 12 volt ignition source. that’s what I couldn’t figure out. the little red wire.
I do have a question. I have had my old one go battery, fuse, then a toggle switch that turns on and off the compressor then it goes to the setup. With this setup, can I splice into that wire and have both red ones go to it? or do I have to have the little one go to a 12 volt ignition source?
