Hey, I checked out our service manual's electrical book and I think I figured it out but I wanted a few other opinions before I tried anything. Our dashes come with a blank switch next to the defroster button, and I wanted to wire up a cutout muffler into my car. I had an idea to kinda hide it by using a second foglight switch in place of that blank to operate the cutout, but I'm not sure if our foglight switch can act like an off/on switch or not.
To me, it looks like if I hook the wires up to pin 1 and pin 3 on the switch it will operate like a normal on/off switch if I leave the rest unplugged. What do you think?
