can someone tell me how to wire the headlights? and include a the dash switch in the equation? I can run a wire direct to the battery and get them to work, so that wiring is complete, not sure how to get the switch to be in the middle of this. I also have a alternator w/ one wire, I dont think anything is running through the regualtor on the firewall, not sure, but dont think so. I am missing headand tail lights. have switches
