It looks like I had already tried the right moves, but, I just didn't force it hard enough.
1. The large connector, as the description says, starts out easily - but then jams tight. It seems I need to use more force.
2. The two smaller connectors have that locking tab; I guess I just have to press down on that locking tab with more force, and then swing the lever to the left (in the picture).
Those instructions you found make it seem intuitively easy! 
This closeup of the GM Module board from your reference shows the tabs that need to be overcome:

Those two should be relatively easy to pull since they're both in the glovebox:
F4 = 20A, Passenger comp/trunk lighting, Windscreen washer system
F9 = 15A, Air conditioner, Heated washer jets [Check Control Module panel]

The clicks 'do' sound weird. Nothing I've ever heard before, at least not when the car is just sitting there, doing nothing (except clicking & sourcing current). I'm lucky I caught it on video as it didn't happen all the time. The noise actually sounds like a relay kicking on and off - but I have no idea what relay that could be.
I admit, it was almost dark by the time I pulled the FSU Fuse F79, so, I'll have to look again tomorrow. I have the car outside, unlocked, with the trunk open, charging away on the charger - so I hope it doesn't rain tonight.
BTW, how much is your active & quiescent current?
