As an update in case someone else ever has this problem, but I kinda doubt it. Fuse #39 ( I/P ELECTRONICS IGNITION FEED ) kept popping with the TCCBrake Switch plugged in under the brake pedal, where it belongs. After about 30 fuses I've determined it had something to do with power steering. With the pump having so many leaking problems I had it replaced. The shop noticed that the upper hard line was pressing a wire harness against the firewall. This hard line could be reversed, releasing the pressure. After they reversed the hard line they noticed some breaks in the wiring harness and fixed them. I suspect the power steering line would shift just enough to push one of the wires in the harness to ground or an adjacent wire. Looks like the previous owner never figured out the issue and just left the TCCBrake Switch unplugged. I still haven't figured out how to get the HVAC activated by my remote starter but that's really low on the list Thanks for all the help and suggestions!

from the GP clusters I've had in-hand.... all 89-90 UB3 clusters(not the half-digitals, though they wouldn't surprise me) will have the speedo and tach go nuts, it's when, not if. I imagine most have by now. SOME 91-93 clusters have the speedo and tach get out of whack. not all, for whatever reason(I'm not sure if it's a build date related issue or not). all will have the check gauges and low fuel light issue, at least once, eventually. GM's choice to use whatever the hell lacquer-like conformal coating on the last ~4" or so of the board seems to cause issues.
