Since the harness is fucocked right now, what you could do is re-task the leading coil wires since everything you need is right there
The leading coil (and this is from memory so bear with me) has two wires that connect to it. G/Y and B/Y. The G/Y should be dead at this point in it's life however, the B/Y is off the main relay and will be hot with the key in the start and run position. So, the B/W wire can be used as the key hot with the resistor wired in place. Then since you're right by the battery anyway, you can connect the "sense" wire directly to the M6 bolt on the fuse block.
I like this, sounds simple enough!

I'd like to replace the whole thing, everything is brittle.

Pressure, yes but oil level is disconnected.

eh, I'd rather have this done by someone with all the tools and materials already in hand.

True, I didn't have them connected on the last tranny.

30 yo wiring is crispy?!?! Say it isn't so

It should be relatively simple, I can only think of 5 wires you needs. Alt charge, Alt control *2, oil pressure and oil level. They should all be on that FE-03 connector

Welp, you can go here (I've been doing business with Joe for a LONG time) and get the kits of the connectors https://prowireusa.com/c-76-deutsch-...ctor-kits.aspx

Just order them with the solid pins. Then you just need this little guy

There's no need. I just break the wires off at the switch.
