Default Metra 70-1857 install

I installed this wiring harness to my Bose Gold stereo in my 1994 Corvette. My question is the harness only connects to four out of the five connectors.
It seams the 5th connection is the “left side speakers”. I noticed it is a little wider(9 pin) than the others?

What am I missing?

I'm about to attempt this same install. What was your solution? How did you run the harness from the stereo to the passenger rear?

A photo if possible, would help. Are you referring to the radio control head end or the end behind the passenger seat? I just installed a new head unit in my 1994 yesterday.

If it is a BRN/WHT wire on a 9-cavity connector, then it is either "left audio out" (head unit end) or "left audio in" (storage area).
