There was not enough information in the first few posts and then the information after is kind of scattered.
How I would do this, IF I think this is going, is to isolate that wire he has voltage on. See where its getting its 12 volts and remove it.
The Neutral switch lug on the Starter Relay, I would just make a 5 inch black wire with a female spade on one end and an eyelet connector on the other. Put the spade on the neutral lug and the eyelet under the bolt holding the Starter Relay down, BOB's YOUR UNCLE!

What does hanging loose mean? Loose from ground point or loose from relay.
So I guess we could ask, where do you ground your starter relay too (originally), since the safety switch was removed? Loose from the relay. If it's not plugged into the relay and it's hot, it's not a ground. Ground it anywhere. Sheet metal close to the relay will be easiest. If it was working and now it's not, something changed. Lights not working, ground wire is now hot. I'd be looking at harnesses for rodent damage. Any fuses blown?
If the results don't match the theory, change the theory.

Put the spade on the neutral lug and the eyelet under the bolt holding the Starter Relay down, BOB's YOUR UNCLE! I'm sold on the idea of running a new ground. (I actually got the same advice from Richard Ehrenberg). Now I need to figure out why the all the gauge lights are out. I checked the fuse and it's good. And when I pull out the headlamp switch I get 12 volts at the fuse. So, unless all the bulbs blew out somehow, I guess it has to be a ground issue. So can anyone tell me how the gauge cluster lights ground? I've tried looking at the wiring diagram but it isn't clear to me.

Grounds through the screws that hold it to the dash ^^^^This! Did you mess back behind the dash, even a little? The dash printed circuit board has (Off the top of my head) 8 pins that are crimped on the board. The connector goes on those pins. They have been known to get loose and snap off. So if you got your mitts back there you could have goggled one loose. They can be reinserted and swedged back on but it is fiddly work. You are only 480 miles southeast of me, I'll be right over.... Really if you were within 100 miles I'd head over to look. But 8 hours is a bit much.

Turns out we were putting car back together from a resto, and it would not start via key. Turns out relay was bad. So I took the bad one a part. Turns out it was pristine inside and the coil was not bad. What I found is that the 2 terminals used to activate the coil are assembled in 3 pieces. Brass terminal, brass rivet, and inside terminal that the coil is soldered too. When I checked coil from inside it was fine at 25ohms. When I checked coil from terminals as the ignition system would use it, it read open.
Turns out on both terminals the inner contact had no continuity to the outside spade, and on one terminal the rivet did not even have continuity to the terminal. So they must have had a heavy varnish/coating that insulated the connection. Really a bad way to build this with 3 independent connections. Having the spade terminal go fully through to the coil wire and rivet would have been much better. No joint and the rivet is only responsible for mechanical binding, not actually continuity.
I clean the rivet and soldered the inside terminal to the rivet head, and on the terminal that had bad continuity to the rivet, I flowed flux on it and heated with solder iron to burn off any varnish, then flowed some solder under the rivet.

There is power at the yellow connector on the starter relay with the key turned to start and if I jump the relay, it will crank and start. when you say jumping the relay if you are grounding the G terminal & it now cranks then what Dragon Slayer said, see why the NSS downstream ain't grounding the G terminal like it should

Elementary electronics, so basic & so simple yet it kicks so many peoples buts, understanding electronics can really be confusing,like when electronic Ign. came out in the early 70s what a game changer.
