QuestionI have a 1954 Ford F 100 pickup. It now has separate wires for tail, stop and signal. I bought LED lights with stop and signal on one filament. Don't know where to start to wire them.
AnswerI'm not a truck expert, and I don't have any information about how your truck is wired, so I cannot be much help to you. I'm surprised that the truck has factory turn signals, they may be aftermarket add-ons. That is what is on my 1952 F2.
Call around to shops that advertise that they install trailer hitches, and describe your problem to them. Most of those guys are pretty savvy at figuring out how to hook up lighting systems to existing wire harnesses. They may have to install a replacement turn signal switch on your truck.
Later vehicles share the same filament for both stop and turn lights, so they have 3 wires, still, but one is for left turn and stop, one is for right turn and stop, and one is for tail and license lights.
If your truck is still 6 volt positive ground, you may not be able to use the LED lights - they are polarity sensitive.
If your truck has been converted to 12 volts, negative ground, it will be pretty simple for the trailer hitch guys to figure out how to adapt to the LEDs, if the turn signal switch has the right logic diagram (it has to know to disable the brake light on the side for which you are signaling a turn). Only fairly modern turn signal switches address this need.
