2000 4x2 ignition

A friend gave it to me last summer, it ran fine but had hood/fender damage, trashed seats and rust. I got it all cleaned up, new hood/fenders/ seats and repainted it to be used as a get around at our hunting camp. Well, I parked it in Oct and for many reasons didn't get to use it all. It just sat. I vaguely recall having to jiggle the key a couple of times to get it to start, really only used it a week or two, but I think that happened once or twice.

I decided to haul it back home and it would not crank. Turning the key did nothing, no click, nothing. I charged the battery before I even tried. It reads 12.7 v at the starter solenoid terminal. When I jump the two terminals on the solenoid, the starter motor just spins, doesn't engage the engine. Key is turned on when I do this.

I ordered a new ignition switch, but wondering if it has another problem if the starter motor just spins. Or does the ignition switch have other safety circuits within it that would prevent the starter from engaging.

I would think it could be hotwired if it's just an ignition switch, but with 6 wires on the switch, the combo options of which wires do what are many. I couldn't find a wiring diagram and would think it would just be a power and starter wire to jump.

Thoughts on what could be causing the starter motor to not engage when the solenoid is jumped ? and any info on how to jump/Hotwire it to bypass a bad ignition switch, if that could be the problem ?

Appreciate any thoughts, thanks...
