Need help with rewiring my dome light in a 1954 Ford Customline

If anybody can help me with this I would greatly appreciate it. I have a 1954 Ford Customline and am rewiring it from front to back with an EZWire Harness Kit. The original wiring for the dome light has two wires, a white and black striped wire and a solid yellowish colored wire. Both of these wires run to the dome light. At the switch the white and black striped wire runs to one side of the switch and the bulb and the yellow wire runs by itself to the other side of the switch. I think the dome light is grounded to the roof by the mounting screws but there are also the same colored wires running to both of the door switches as well. I think that the door switches are grounded to the body as well but I have tried wiring this dome light everyway I can possibly think of and I cannot get it to work properly. I don't know if one of the two original wires is a ground or a return wire. I have used a test light and cannot get a definite result either way. I am at a loss. The new wiring harness only has one wire going to the dome light. Help me please before I blow more fuses. Thanks.

naystcb,

Should be that one of the dome light wires gets full time 12v, and the bulb comes on when the other wire finds a path to ground through the door jamb switch. Make sure you have the right bulb in the the dome lamp. The bulb has an insulated base. It should have two terminals on the bottom like a turn/tail bulb, but only one filament.

Hope this helps...

Check this http://www.oldcarmanualproject.com/t...re5765-194.jpg it is for a '57 from the Old Car Manual website. What you are saying is correct, but the secondary wire from the domelight is going back to the headlight switch. You may have to add that wire in. And yes... the car body would be your ground.

OK,

Disregard my last post. I was thinking of a GM dome light system.

The diagram that Kevin45 posted shows that the dome light system on a Ford is switched on the positive side, not the negative side of the circuit.


It should work if you wire it as follows:
