Wiring Question

[tomrex]

Ok, if anyone has read my previous posts, I have a goofy dash board. Once in a while (more often than I'd like to admit) my gauge cluster goes insane. I loose all of my electrical gauges, the only ones that work are speedo, tach, and oil psi. I also get a flashing message center with just about everything in the book. I found that if I pull the harness out of the gauge cluster when it's doing it...and put it back in...problem's solved...for a while. I wondered if anyone would have any suggestions or if anyone had a dash wiring diagram. Let me know. Thanks a million. Tom. BTW: It is s 2000 Sierra 2500 with the 6.0, 4x4 and automatic. Thanks!
