So, I'm trying to put the OEM head unit back in for unimportant reasons. On the wiring harness there are three dark green wires, two dark blue, and two yellow. Now yes I've looked at the Wire Diagram, but it only shows one dark green, one dark blue, but both yellows. I'm wondering if there's anyway to figure out which one goes where without pulling the trial and error process. Seeing as how one yellow is a power wire, I'm not trying to try anything risky quite yet. And my voltage meter isn't giving me an accurate reading. There are sixteen wires on both ends, and I'm trying to figure out if any of the duplicates have to be specifically correct?

Please help ):
