While redoing a botched radio install on my son's 1992 Accord EX, I came across a loose wire that was running behind the rear of the ashtray. As you can see from the picks below, it looks like the wire was/is part of a plug/receptacle somewhere in the dash. On the photo with the arrow, it looks the wire runs behind the ashtray and then back towards the stick shift area, even though I cannot tell for sure if it does so or leads off somewhere else. Additionally, when stretched to full length, the wire looks long enough to lead to the HVAC control area.

Any help would be greatly appreciated.

 

From the pics, it looks like a lone wire, which looks out of place

I would trace the wire back to the main harness to see if there is a branch on the where wire harness that wire belongs to. Then see where that branch of the wire harness goes to.
