As for the speaker wire, we're on the same page mostly, I'm not expressing my view clearly. What I was thinking is the harness is the same, but the wires would either be cut off about foot from the harness, or hanging behind the dash somewhere. I don't see a point to running the wires (but I agree with the '1 harness = less cost' mantra) to where speakers were never installed. That's just me.
