Did I find the right spot? Won't start.

By "won't start" I presume you mean "won't turn over"?
Logical troubleshooting.
Can you jump the starter relay and it spin? If so, then it's the wiring to the relay from the ignition switch.
If not, then it's wiring from the battery through the relay to the starter. Can also be the NEGATIVE run.

Well,first, you need to figure out what's NOT working, don't you?
To jump it, take a pair of pliers, and with the relay removed, jump across the two active wires.
Which ones are those? Well, you'll need a wiring diagram for a 1992 (which I don't have); RockAuto lists the factory service manual, printed by Bishko for Chrysler, on disc as a PDF for about $23.
Someone else here may have one and can kick out the page needed out of the PDF.
There's always the possibility of the ignition switch itself failing; you'd need to check it, or just toss parts at it, to find that out. I'd test myself.
Suggestion: Harbor Freight, if you have one in your town, will have some cheap multimeters that will do the job good enough.
Checking the parts list (from the FAQ here), I find the original part number for the starter relay is 4504215. I find that has as Bosch style pinout; I'd jump pins 30 and 87 on the relay and see if the starter spins over. If it's not labeled, grab a Bosch SPST relay and use its labeling. Or use an image like https://www.rockauto.com/info/903/1R1007__ra_p.jpg .
If that works, it's the wiring to the relay, or the relay itself.
With that checked, I'd get a friend to help turn the key to START and see if you get 12V across the 85 and 86 pins with the key at start. Also, I'd see if you get continuity from either to the chassis with the power off.
Due to age, I'd SWAG that the ignition switch is failing; but that's enough of a pain to swap, I'd really test the signals first.

There's a splice that looks kind of like a fuse holder there on a lot of our trucks. There might be another matching end sitting under where you're looking.
The wiring diagram will be in the factory service manual, printed by Bishko Publishing for Chrysler.
They can be had on Ebay used; several places new. The disc version (a PDF) is usually right under $23 at RockAuto.COM .
