Rear light harness

I'm installing a new rear light harness in my 1968 RS/SS and all is going well but I have one question.
Not too far from the main connector going into the fuse box there is a very long white wire. It is long enough probably to go all the way back to that trunk but I have no Idea what it is for.

Thanks
Mike

Re: Rear light harness

Mike welcome to the site. The white wire is usually the dome light wire. I sent you a wiring diagram for a 68. Check your e-mail.

Re: Rear light harness

Thanks for that.

Ok, one more question. What route does the wire take to get to the dome light? Does it go up the drivers side "A" pillar?

Thanks
Mike

On my '69, the dome light wiring runs up from the rocker, over the driver's side wheelhouse, behind the interior sail panel, and then comes out of a square hole in the side roof reinforcement directly over where the door glass and 1/4 glass meet, then it is clipped to the roof support rib up to the dome light.
Would think all first gens are the same, but don't know for sure.
BTW, the dome light wiring should be twin white and orange.

That sounds similar to the routing on mine. There were white and orange wires that run to the light.

Re: Rear light harness

Ok, with your help I have figured out the dome light harness but there is still this very long thin white wire that comes out of my new Classic Industries harness.
The harness is the rear light harness and the white wire in question comes out of the harness about 24 inches from where the connector is to attach to the fuse box. The wire is several feet long.

I will snap a picture of it tomorrow.

Thanks guys.
Mike

Re: Rear light harness

I think that white wire is for your dome light switches that are screwed in the front part of the door jam. When you shut the door it pushes in the switch and shuts the dome light off. one on each door.

Re: Rear light harness

The white wire 24 inches out of the harness and several feet long could be the pass door switch wire routed through the dash.

Re: Rear light harness

My 67 had the drivers side switch with 2 wires and jumped to the pass side. So I guess you would cut the wire at the drivers side switch and then put both wires in the switch and crimp it. the run the wire over to the pass side

Driver's side has a 2 terminal switch, for the key buzzer.

Re: Rear light harness

Ok, here are a couple of pictures. You can see where the white wire comes out of harness and it is about 5 feet long. Also note the connector is a barrel shape end.
I measured voltage and when the drivers door switch is pushed in (door closed) the wire has 12 volts and when door is opened it has no voltage.

I know it has to do with courtesy lights but just not sure where it goes.

After I figure this wire out I have a purple with with no home from under dash, that is my next mystery.

I hook battery up and it looks like my interior lights are all working (dome-rear of console-both kick panels).

Re: Rear light harness

This is a picture of a stock harness. The long white wire goes to the passenger door switch, the short white and black wire is for driver's door switch, the orange and white connector is for courtesy light under dash. Your setup will need a double contact driver's door switch. My car was a early 67 with no key buzzer so I had only white wire to driver's door switch. I think you can make out the connector on the switch looks like your connector that you call a barrel connector.
The reason you get 12 volts from the white wire when the door is closed is because the voltage is going through the bulb and the circuit needs a ground which is this white wire. When the door is open the drivers door switch is providing the ground and you get no voltage from the white wire.

Re: Rear light harness

Yep, that makes sense. Thanks a lot for the picture and explanation.

Now I have to start the investigation for a purple wire with no home.

Thanks
Mike

Re: Rear light harness

Purple wire went to a rotary switch along with a brown wire. I think the switch either went to a rear defroster fan or for speaker control. I owned the car now for 36 years and I think I remember I use to have a rear fan in the package self.

The car is a real SS/RS 396/375 front 4 piston caliper car.

Now it is a 548 roller motor and its a tubbed.
