Engine harness ground locations - Who can name every location?
 
Quickly, who can name every engine harness ground location for the engine harness? I just want to give everything a good once over :) Most specifically, where is the ground wire located that's for the 02 circuit on the pass side? The more info you guys could provide the more appreciated I'd be.

Thanks in advance.

Off the top of my head. 1 main ground wire on drivers side of block, and 2 grounds on the back of the block for o2 sensors. This was on my 2000 wire harness.

Does the pass side 02 sensor ground hook up to the top of the block on the pass side? I tried cleaning and reattaching that one already. (The one that's to the left of the oil pressure sending unit)

I only had one on the side of mine, and now that I think about it, I might have had 3 on the back. I marked all the heads of the ground bolts with a sharpee when I did my motor swap.
