Ok, here is the ground wire install I have done. It needs a little bit of cleaning up, but It's a start.
This was effectively A free mod, as I used wires from a grounding kit that I bought years ago and never installed.
First Wire I attached was the Alternator.
I used the power steering bracket because It was easiest to reach. This Is just a nut, and I put the ground behind the existing bracket. The wire is tucked in behind the fuel delivery wiring under and behind the plastic cover.
Next I ran a wire to the Block.
This is attached to a portion of the exhaust manifold, in front of a bracket that is pre-existing. I would have preferred behind, but that was not an option due to the size of my connector and the bracket itself.
Then I tied the 2 Engine Grounds to a third wire that made the travel to the Body Ground.
This was to make up the fact that my wire wouldn't quite reach all the way across the motor bay. The body ground cable came apart on my, and I had to re-crimp the wire end. This will be replaced in the future, but works fine for now.
Ran the battery connector wire and the engine ground wire under the fuse panel.
I used the existing body ground that attaches directly to the battery.
This connection pretty much doubles what I have for the ground running to the battery. I will update the cable end at a later date for a cleaner install.
In the future I might go ahead and ground the throttle body and the transmission, but those are not necessary, and I already have noticed that my throttle response and idle are greatly improved. I'm not sure about light dimming yet, But will find out as soon as possible.
