firewall ground - to where?
 

Ok guys putting in the new engine, i have labelled a ground up high on the firewall, just to the left (toward midline) of the bracket that holds the wire harness, but I'll be darned if i can't find what wire i removed from there. anyone have any idea? or could go take a quick look?

Black w/ yellow stripe? Bolts to a stud at the rear of the head on the passenger side.

Thanks Cre
