Found this earth cable coming up from just underneath the plenum cover, and also found another one quite near it (attached to the bodywork) but not attached to anything else.
Heres the pics:
This is one of them, that goes down a bit, cant see where? anyone know?
And this is the other one, again with a ring connector on it, but this one is actually connected to the bodywork, but nowhere else!
Do the two connect together?
