Default Inlet manifold earth wire?

On a 4x4 cossie there is the wiring loom which bolts to bottom of plenum cover and there is a seperate earth wire coming off the loom.
Where does this go??

Cheers

In one of the two accelerator bracket bolts but I 'm sure that this applies to 2wd cosworth. I own a 4wd and doesn't have earth cable on the inlet manifold.

it goes to one of the rear plenum to manifold bolts, the rear lower corner one iirc,

its the ecu earths, and must be earthed at that place to avoid signal noise

I only ever had 1 earth wire point, was two wires in one connector fitted onto a bolt on the throttle bracket, never had any trouble, both my L6 looms were the same as that.

Wrong by me : I thought that the wire was coming from the front side of the inlet manifold but as above if it is from the rear then on the bolt at the lower corner of the manifold.
