Rear tail light ground

[Robert T.]

My lh rear stop light wont work. It had been working for ever but it broke lose, not attached to the fiberglass rear. when I removed lh rear tail light assembly the pigtail had pulled loose. I reconnected, but while looking at wireing I see where there is a ground connection that has no place I can find to connect to metal. Looking at manual, it shows it connecting to studs on assembly, with a nut holding behind fiberglass. What am I seeing wrong, how can ground work against fiberglass?

Re: Rear tail light ground

Bob, the ground comes from the main wiring harness going to tail lights. It then loops to each tail light housing thus making all four housings ground for the light bulbs. And yes your correct - the fiberglass can not be a ground.

Alan,
Thanks, I see where it looks, do I not connect the ground look circle to anything?

Alan, Thanks,
I see the wiring loop. Where do I connect the ground connection for LH assy. The connection will not reach to metal.

Re: Rear tail light ground

We are looking at the left (driver) hand side rear parking lights from the bottom up. Notice behind the outside light (rt in picture) is the harness from the front of car. Very thick black looking wire, but really harness with taped wire.

That harness has the black ground wire in it. The black wire loops down to the lower nut. At that point a brown wire & the black wire are joined via a round spade connector. Said brown wire then goes to the inside parking light and is terminate under the lower nut by a round spade connector.

Hope the picture answers the question.

My vette is 64. the 2 wires go to the connector that goes to bulb. you can not see both lights at same time.
thanks,

Re: Rear tail light ground

Robert, that main harness has five wires which exit above and between the two parking lights. Two wires go to each parking light and the fifth is the black ground which goes to lower nut on outside light.

Now I re read your post and may not be answering your question.

Did notice you talked about "the pigtail had pulled loose" which I assumed was the connector however if the connector is still solid and it was those wires coming out of connector which pulled loose from some place - then Bubba been there.

At this point I'm a little confused as to what problem is! Can you discribe again but with different words. Thanks
