Alright, after going thru my wiring harness, i noticed that i have a wire bolted to the back of the block and it goes about 3 inches and stops at a connector. I looked at the manual and it says "engine ground", but doesnt say what it is connected to.

I have the negative side of the battery hooked to the block itself via starter bolt, but can't figure out what this one does.

All help will be appreciated.


See att. to know what I'm talking about

 

#10 looks to be the transmission bellhousing to firewall ground. That's the only ground I can think of in that area. The connector goes to a spade connector that's bolted to the firewall.

The one circled near #11 is the condensor for the oil pressure gauge. One side bolts to the engine, the other side connects to the harness.
