So instead of running a wire from the other contact on the drivers door switch. I need to tap off of that wire that is coming from the dome light to the first contact and go to the other door switch and to the headlight switch? QUOTE]
If you run a wire to your passenger door switch, and then run that wire to the driver's door switch, that will still work the same as splitting the wire and running another wire to the driver's door. As long as current can flow to both switches you're good to go.
