Rewiring my '69 Dart and I cant' tell from the wiring diagram which wire is power feed to the dome light and which is ground to go to the door switches. The other thing is that both wires are black. There is a "T" type connector at the end so I was hoping that one of you knew and could point out which is power and which goes to ground.
 
dome lamp wires are supposed to be yellow.
 
The door switch wires are yellow but the 2 wires coming down from the dome lamp are both black......
 
I don't know. 12 volts goes up there, through the bulb and down again so those could be both black. No chassis ground at the fixture.
Yellow supplies a ground at door jamb switches and at headlight switch. Some have a delay timer tied in this circuit also.
Good luck with it.
 
REMEMBER one thing the door switches switch the ground and not the power (hot)
 
Either,, the bulb doesn't care which way you get power/grnd to it..

This is exactly what I was starting to wonder. Since the wires aren't color coded, maybe it didn't matter which way the bulb was getting the power. That's a big help. Thanks!
