Engine bay ground connection points? Diagram?

Anyone got a diagram of ground connection points in the engine bay, including on the motor? Didn't take any pics of this and have dropped the motor back in (kinda, still 1/2" of ing wiggling onto the tranny to go) and need to replace the battery cables since the originals were buggered.

Oh and I scratch the pretty paint on the oil pan getting it in. BASTARD! haha.

I have the FSM but there doesn't seem to be a good physical location diagram in it...

There's also a loop to be bolted down somewhere, coming out of the main harness down from in between the two pairs of intake runners... Can't remember where this goes. GRR

Will take some pics in a few and post here.

Here is a pic of the connection I can't remember where it goes.

Also is a pic of the battery cables I pulled out. Obviously the end with large the green cap coming from the battery positive goes to the starter; where does the other loop end coming from battery negative go? Chassis or engine ground but where? CONFUSIIIIIIIONNNNN. Hrrrrmmm. HALP

Also 2nd question: Where is the most convenient location to get +12v and a ground in the cabin? I need to hook up a tach and oil pressure gauge that require 12v apparently.

I'm starting to wonder if this thing was (is) missing a motor to chassis ground cable... I read a lot about "three wires", but I only had (have) the two shown above... The only other connections to bare motor metal are the firewall to cyl head at the rear, and the black wire coming out of the alternator cable bundle that goes on a bolt holding the PS pump bracket. Is there supposed to be another motor to chassis connection somewhere?
