ok, so I tried connecting the deck to the wires and I couldn't figure out where to mount the ground wire so I ran a wire all the way to the battery to test it out... turn it on, nothing. where does the harness run? maybe it's disconnected somewhere along the line? any insight would be good... Also, there's a bundle of 4 wires for the stereo, one is constant power, one is running power and then there's two more, any ideas?
