not sure if this will help or not... http://www.ls1truck.com/forums/lsx-t...ol-wiring.html

I noticed you said originally you eliminated the drac. How did you wire the speedo without the drac?

direct from the PCM to the instrument cluster wire. AFAIK the 1991 doesn't have a DRAC module, not for sure on that one though. My friend had a 1990 and it didn't have one, at least in the same location behind the glove box.
