Defroster switch hot wire?

I'm installing A-pillar gauges and for the life of me I can't find a wire that's hot only when the ignition is on. I have a vague recollection of tapping into one in the defroster switch when I put gauges in my LX, but that was many moons ago. I used a circuit tester on every wire going into the switch and got no hits, but it's got to be getting power from somewhere. I also recall a tech article from tccoa that mentioned the proper wire, but a) I'm not sure if that applies to the SC, and b) I can't find that article anymore. It might have been at the now-defunct mn12performance site for all I know. Anyone know of a good ignition hot source in the gauge cluster/lower dash area?

What year SC? I only have limited EVTM's here in MI.

94 SC, sorry...

Here are a few to try.

Ignition switch in RUN

The Blower Motor inline fuse holder (Grey with yellow stripped wire.)

ACC 10 A fuse (Has power ignition switch in RUN or ACC position)

Cluster 5 Amp fuse (Has power ignition switch in RUN)
A/C 10 Amp Fuse (Has power ignition switch in RUN)
HO2S 10 AMP Fuse & Anti-Lock 10 AMP Fuses (Has power ignition switch in RUN)

Will,
