I'm doing a new stereo system. Tonight the interior seats and carpet were removed. Putting Damplifier Pro (like Dynamat) on the floorpans. There is a rear speaker lead on the passenger side that runs behind the HVAC down the firewall. I yanked out the remains. Somebody before me cut out the rear trunk harness, so I don't know the specific square or round hole it went to back there.
Also did the M&H intermediate harness tonight, too. It was a pain up by the fuse block. The original was within that long, flat plastic canal previously mentioned. Repro is wrapped. Pulled out the plastic canal since new harness would not fit anyway.
