I know it has propbably been answered before so please be patient with me. I have transplanted a 02 LS1 5.3 into my 1985 Crew Cab shortwheel base conversion. I am at the point to where I am trying to repin/install a 1990 Blazer instrument cluster into my 1985. Does anyone have a guage wiring schematic for a 1990 Blazer? Thanks!
