Two grounding wires not sure where they bolt to for a 2.2L 1993 Toyota Camry.
 

Finished doing an R&R on the cylinder head on a 1993 Toyota Camry 2.2L. Pretty much have everything together except timing belt, alternator and some other some smaller items. I am in question now where two grounding wires go. They are towards the back left near the firewall coming out of a harness. There are two of them both have same connectors on the ends. They would have to be bolted maybe to something maybe intake manifold, firewall iteself, somewhere, but now sure. Cannot find a spot they will fit on to.
Maybe someone has an idea where they go.
