With the throttle issues I'm having, thought I'd check the grounds on the GM harness. Manual says there are three, but I can't find them. Anyone know where on the harness they are?

I know at one time there used to be a ground to the injector harness, one to the throttle body and one to the distributor (obviously not a DIS) so I would assume to the coil harnesses..

There are two wires that they put into one ring and one that is on its own ring. Both are in coming out of the harness on the back of the engine. Both should be connected to the heads.
