Checking the Wiring of the Assist Solenoid

[KM7]

1991 Ford 5.8 Ltr
I disconnected a few wires from the assist solenoid in order to gain more access to the valve cover on the starboard side. I thought I had taken enough pictures, but apparently not #@&.
I have the OMC shop manual and the wiring diagram; see attached.
The reason I'm questioning my wiring is that while it does match the diagram, it does not seem to match the way it was before I disconnected things. I may have wired it incorrectly before, and I just never knew it. Since the assist solenoid is basically a switch that closes when energized, it might have worked fine with the 2 main lugs reversed.c

Yellow lug wire goes to starter solenoid? So you or another have changed the starter to a different type?

The Ford starter has one large wire connected.

I was wondering about that too!
I don't have the Ford 5.8 in my OMC shop manual (they weren't using it yet) but I do have the diagrams for the Ford 2.3 and the Ford 429. Gonna look at it now.
OK what I see there is exactly like the pic above with one difference:
1) top Purple/black ignition wire
2) left side, thick cable to starter
3) here's the difference: right side, thick red cable to battery, two thinner cables (one goes to trim relays, the other goes to the B+ terminal on the alternator. Yours may be different because they changed the design of the trim relays between mine (1988) and yours. Yours go to Circuit Breakers IIRC, that's the difference.
4) Bottom, yellow/red starter wire.

looking back at your schematic, it is basically similar with that terminal on the right side which feeds 2 circuit breakers, one of which feeds that trim relay assembly (different than the older style with 2 large old school relays) and the B+ terminal on the alternator. So, the difference is that they added the circuit breakers and integrated the 2 separate trim relays into one unit.
maybe post up a pic of your Ford starter.
I know in the old days Fords (automotive) usually had the starter relay on an inner fender vs the GM and Chry Co which always had it on the starter.

The slave solenoid battery post is often used as a junction for all wires carrying a continuous +12VDC power. So if you have any wires that are unconnected, see if they belong there.
