I leave my little bluetooth OBDII unit plugged in all the time, unless I know I won't be driving for a few days in a row. No issues at all. Mine doesn't draw a ton of current, just a couple LEDs and the little bluetooth UHF radio transmitter.
Your issue with a freezing cluster sounds like a symptom of some deeper electrical issue. Not sure where to start investigating that, but you might consider looking into it. I wonder if there's some loose connector somewhere that looses continuity during heavy vibration?
Maybe my adapter unit is defective or something... The issue only happens with it plugged in.
I guess it wouldn't hurt to try a new adapter with this new cool application.
