Gauge Swap Help And Wiring Diagram Needed

[wildmanaaron]

I just recenlty purchased a 1981 Blazer that had a non-gauge dash, but with two mechanical SUNPRO Temp & Oil Pressure gauges. This set-up was an ugly eyesore, so I went to the local junk yard and picked up a gauge dash out of a 1987 C/30, 350 TBI. I kept the pigtail off of the C/30 dash as well. Now I understand that I need to move the pins around on the end of the gauge harness that is currently on my Blazer, to match the printed circuit found on the back of 1987 model cluster. But this is where the story goes sour......

I have the Haynes manual for the 73-87 Chevy Trucks, but it does not have very clear or specific diagrams for what I need. I was wondering if someone had access to some better diagrams that would make it a lot easier for me to change all of this over?

Any help would be greatly appreciated!
