On our 98 Blazer which used to be our only toad and still pull it occasionally, I have pulled the #11 Fuse labled Cluster and also the #4 labled Gauges. Actually the only time I ever had a problem was when the battery was going bad and hadn't showed any signs yet. After a near 600mi. day it wouldn't crank. Put a battery charger on it and in a few minutes it cranked. Pulled those fuses for the rest of the trip & had no problems. Had the battery load tested and it was on it's last legs. Have had no problems having to reset clock, etc. with those fuses pulled.
