99 G101 tracing

Tracing wires for ground from G101 front of the block on the coil bracket.

Does anyone know where these splice off, I have two black/ tan wires to pcm. G101 has two ring terminals with four wires, two black/tan on a ring, and one black/tan and a black on the other ring.
I can trace and rest the black/tan to the pcm and have decent continuity.

Ohm continuity test the black, black tan ring to battery and I don't get anything. I gotta be doing something wrong, do these tie into the rear G101. Wire diagram not helping exactly, I assume they become another wire color then???


Any idea where I can trace these to would be greatly appreciated!

That first picture, I think the third wire is black w/ white stripe. Those tend to look like tan after a while.

According to the wire diagram they are all black/tan or solid black.


What I'm having trouble finding is the G101 grounds on the back of the block.

What do these run to? Tcm,02s,tcase? I'm trying to find the end of them to test, the wire diagram doesn't show this.

Thanks all
