Need a color coded wiring diagram for a Model-A. The one that came with thee wiring harness does not show which color wire is the high beam, low beam or ground please help me!
Thanks Jeff

What wiring harness brand? There is no ground wire on headlights-the light is grounded to the car. You may want to get back to the place where you purchased the harness and ask them.

Ok my wiring diagram shows black/green black/red black/yellow. What wiring goes were. I am trying to hook up 6-volt Quartz light kit. What color is what.
Thanks for all the help.

Sounds like you have a harness for a two-light headlamp, one with the parking lights built in to it. Easiest way to determine which is which without a wiring diagram in hand, is to use a volt meter. One of your leads will be for high, one for low, and the other for parking lamp. The position on your switch should be 7 o'clock for parking, 5 o'clock for low beam, and 4 o'clock for high beam. Whichever lead gets the juice in these positions will tell the tale.
