Gauge Circuit Shorting Out

Finally got my 93 Suburban running and now the Gauge Fuse keeps blowing. I would like to find a wiring diaghram to determine everything on the circuit. I have in plugged all the sensors and it still blows.

I want to trace the wires but I am not sure which wire would affect this circuit. I can move the wiring harness and the short opens but as the truck runs it comes back.

Any help would greatly appreciated.

Update:
found the wire shorted under the dash but don't know where or where it connects. I unplugged it from the connection block under the driver side panel that has the buzzer. It reads to ground and the fuse will not blow. It is a pink wire with a black stripe and the connection is marked BLUE. Not sure what that means.

Thanks

Update again.
Unplugged the wire that was shorting and can't see anything not working. Guess I will leave it off and see if I can see what doesn't work.
