Thank you Lambert!
I expected that eventually I would find out it was all along in front of my nose and die of embarrassment: you're absolutely right. I was looking in the front of the bike as it seemed that is where it is located on the 1200. Shame on me for opening THAT fuse box yesterday, reading the labels, and insisting on looking somewhere else.
To summarize for everyone, the "front fuse box (A)" means to designate the fuse box that controls the front equipment, not the location of that fuse box. The "inside the left panel" location is somewhat misleading IMO; it means left when facing the rear of the bike under the seat, not some mythical inspection panel located on the left of the bike. The "rear fuse box (B)" is located on its right.
So now, while I made some progress with your help, I am no longer sure that the 950 uses relays to command the high and low beams. The point of searching for the fuse box was to discover those magic relays hidden behind it and place a one-way shunt between the energizing wires for high and low. I'll keep you posted.
