Chevy 2000 blazer zr2 Bose Wiring Diagram?

I am trying to install a new stereo in my Blazer that came with a BOSE stereo. None of the wire colors match up to the new wiring harness. I have look everywhere found one site that had the instruction but you had to pay for their download app. Of course now the app can't find the file to download. Does anyone know the wiring for this stereo? Stereo was manufactured in 7/98. Please help before I rip my hair out. Thanks!
