Installing aftermarket stereo, need correct pin out info and wiring colors for all three harnesses

Trying to install aftermarket stereo but not sure what harness I need for my SUV I have already purchased a few that were supposed to work for my vehicle, but the wire and pin outside don't match up. My SUV has three harnesses coming out from where the stock 6-disc changer head unit was, but I can't figure out what the wires go to on one of them. Looking for correct pin out info and wiring colors for all three harnesses on the vehicle listed above Eddie Bauer Edition.
