I am replacing the dash on my 71 Chevelle with a custom aluminum dash (of my own engineering). I want to replace the old head light switch with one or more of the toggle switches that I plan on putting in. My question is, what wires do I need to be concerned with and how many switches do I need to dedicate for this type of operation? I believe it will take two switches, one for the head lamps and one for the marker lights. I am not concerned about dimming the dash lights.Has anyone else done this before and do you have a wiring diagram for it.
