1989 radio wire colors

Hey, Im new to the forum and I just picked up an 89 blk notch. I want to install my system, but I don't know what the wires on the m100 wire harness are to install my head unit. Can anyone please help me.

first we need to find out if you have/had a premium sound system. Is there a hexagonally shaped metal box with a bunch of holes in it in the bottom center of the dash? Two hrns's?
