Hi guys, can you tell me what earths out down behind the passenger headlight please?
I'm curious as to what part of the fuse box earths here

Cheers

Everything around the bonnet earths at the point you refer to, except the engine management (top of RH turret), and (I think) the fuse box. I'm reasonably sure that the earths for the relays in the fuse box , that need an earth, go down into the cabin and earth on the bulkhead behind the glovebox.

Ok thanks mate.
I realised that I did not have those earths connected when I had my starting issue which is why I asked.

The car is still at the fabricator so I haven't had it back yet but I wondered if that would have made a difference

Definitely nothing on that earthing point is anything to do with the engine. The important ones for the motor are the top of the suspension turret and the main engine to body earth strap. IIRC, there are also some earths for the engine to the inlet manifold or somewhere close on early 20s.
You could also include the earth point on the LH side of the rear seat, where the fuel pump earths, as the engine won't run without that one either.

As preventative measure, good idea to unbolt check & clean the eye terminals on those earth points.

I had an issue with a non function cruise control.
Cleaned up the engine bay earth and presto it started working.

As soon as the car comes back from the fabricator I will be going right through it. I'll definitely give them all a clean up
