1972 911 tail light earth point: where?

[Porboynz]

The tail light housings have the std round plug through to the engine bay and a seperate earth wire that looks like it should connect somewhere in behind the housing directly to the bodywork. The car is being reassembled after a bare steel repaint etc and I would like to keep things original. Before I did the restoration I had a simple earth wire attached to the chassis with a rivet and star washers etc. It was a little rough but it worked OK. Can anyone tell me where the earth points should be? A photo would be really helpful. The RHS housing also has another pair of wires that go to the oil tank level (tank up under the guard on the 72) Alternately I could use a spare pin in the round plugs to take the taillight earths back to the main earth stud by the CDI/relay panel.

The ground wire connects between the light housing and the chassis under housing mounting screw.

It's been a while, but if I remember correctly the earth (ground) wire should have an 8mm eyelet, which connects under the head of a bumper bracket bolt, or possibly between the bracket and chassis (where the bolt passes through).

Mine went to a bumper bracket bolt.

Ditto, bumper bracket bolt.

OK thankyou, the bumper mount bolt it is then by concensus.
