I'm trying to install an aftermarket radio and amp, but I've run into the craziest problem. So after figuring out it was a DTS and I did not have a Bose system but a premium AC Delco 8 speaker system, no matter how I word it I keep getting the same diagrams but none of the colors in the diagrams match the actual wires I have in my car maybe a few but otherwise it's a guessing game.

This is the diagram they show for the 8 speaker system. Do they match up.
