I don't have the original dash anymore. I have a console that was made with autometers, and I converted the from end to a 70' from 71' and wired the high beams in. All no problem. My headlamp switch is something I want to replace, I only need a switch for on and off, and the high beam switch but thats on the floor. No Dimmer needed, etc. Would it be easy to wire in an aftermarket on off type switch where the headlamp switch is?
