Turns out I didn't need a stop lamp switch. When I removed the cover under the dash to access the switch, I discovered that some SOB had cut the red wire on the 4-wire connector to the switch.
The way it was cut, it looks like it was the victim of one of those dreaded scotch-lock taps - the break was more of a tear than anything.
The cable bundle which ends in the connector to the stoplamp switch was just long enough to plug into the switch. There wasn't enough wire left at the connector to do any sort of under-dash repair - barely 1/8" remained.
Tracing the path of the cable revealed that it was actually long enough to pull out from under the dash for an easy solder repair, but only if it could be disconnected from two retention points - one on the brake pedal frame (easy), and one on a zip-tie at the firewall behind some electronic module.
Accessing this simple attachment point to cut multiple tries (translate multiple efforts to squeeze into the drivers floorboard on my back) over the course of 1 hour. It would have been far easier if I had been born with another elbow between my wrist and existing elbow - that and be less "broad of shoulder and ample of girth"...
Anyway - soldered the wires back together, reinstalled the connector on the stop lamp switch and went out for a "cruise" - all working again as designed.
