I have dual cutouts on a custom setup. Just about any exhaust shop can install the cutout. Just cap it off when you leave the exhaust shop. Then you really should be able to install the wiring part. It doesnt get ANY easier. Its a snap. Tw wires and your done...one power one ground. Mount the switch anywhere. I like mine. You just have to be careful going over bumps. I ripped the wires out of one of mine already.
