1969 cutlass s ac car

just got the dsh back together and have one last wire with no home,,,the single blue wire is just above the cold/warm cable mount on heater/ac box. it has a male connector on the end with a blue sticker.seems like it goes up the firewall .any thoughts?

If it goes up under the carpet at the firewall AND heads backwards towards the back of the car, it is for the rear radio speaker.

thanks, im going to ohm it out to the back of speaker shelf, i know there are 2 original wires back there on are lined up for a speaker and the other for the rear window defroster. just ordered the chassis shop manual for easier trouble shooting.
