Smile Blowing the gauge/brake light/blinker fuse

Hey guys, I need some help. My 90 is blowing the fuse that controls the brake lights, blinkers, and fuel/temp guages. The fuse blows immediately when turning the ignition to on and before using either the brakes or turning on the blinkers, so I suspect the wiring related to the two guages. Any suggestions on where to begin? Anyone had a similar situation?

I suspected the rear center brake light fixture because it has some corrosion, but ruled that out because the fuse blows without activating the brake lights. Am I right to rule it out? Any other way that circuit could be the problem?

Thanks in advance, my arm is getting tired of being the brake light and turn signals.....

+12 goes to ground somewhere...
with everything off, unplug the fuse, connect a 12v test lamp where the fuse was connected and check everything related to that fuse until you will find the problem where the test lamp goes off.

so that is very helpful...and reminds me that the circuit problem could be anywhere despite the "off" or "on" position...starting with my brake light suspicion...stay tuned.
