88 STX 4x4 Manual trans/tcase- Looking for pictures of electrical connections from main harness to trans...

I have an 88 Ranger Supercab STX 4x4 that originally was a 2.9l / 5spd truck. Not sure if it had a manual tcase originally. It was just a roller when we bought it and is now a hybrid / swap build. We now have a NV3500/NP241C installed but not wired in yet.

I am having issues connecting the electrical connections to the tcase and trans.
Does anyone have some photos of the electrical connections from the main harness to the stock trans?
I hooked up what I believed to be the reverse indicator leads for backup lights, but had no luck.
The wiring colors I have found do not seem to match up with the manual's schematic listings.....
Looking for some guidance, please.
