When you guys wired your lighting wire for your tach did you wire it so it dims with the rest of your dash lights??? If so which fuse did ya use????

Pull the headlight switch out, take a test light and find the wire coming out of the switch that runs the dash lights, tie it into that wire so it will dim with the dash lights, i done that on my old dakota i had. Worked like a charm.
