That makes life easier. You didn't blow the fuse, right. smile Looking at the factory wiring diagram (which leaves some doubt) the power comes in on a grey wire which is on a corner of the panel connector and is tie to the heater light, then a 5 amp fuse on the fuse block. My best guess is the other side of the fuse is a dark green wire from the headlight switch. If you have a test light you check to see if the light varies as you turn light switch knob. I hope GM as gotten better at wiring diagrams.
