Re: 1940 Turn Signal Wiring Diagram

I forgot to add a sentence about front parking lights . . . if the car never had turn signals from the factory the front lights are not likely dual filament, therefore they need to be managed much like the stop lights. That is the turn signal shares a single filament with another function. Gar your wire count might be as high as 8 to cover the front bulbs. If we call the parking input power as circuit 8, then 8 & 4, and 8 & 5 will be common with the signal switch centered. With the switch in the right turn position then 2 & 4 are common, and 8 & 5 remain common.
