Mystery Wire

[Voodoo]

Reassembling the 66 Charger after installing the new harness and I have one mystery wire that I am hesitant to make an assumption on. I could not find a confident answer in the wiring diagrams in the Charger Supplement either. It is a black wire with a white tracer, and has a female spade connector (with no plastic shroud) on the end. It protrudes from the harness behind the Temp/Oil gauge, and is long enough to reach either something on that side of the cluster, or possibly something for the radio head unit. Does anyone know what this wire could be? I don't have the best pic of it, but you can see it labeled "?" in the photo below to get a sense of where it comes out.

Does it go the the heater harness? This is why there is no plastic connector, it goes in the heater switch plug. Usually the heater wiring doesn't come with the new harness.

Holy crap you are right!!! I currently have the heater box out for rebuild and that explains why I couldn't find what it connected to haha. Thank you so much!

That harness would be attached to the old dash wire harness. Plugs into,the blower switch and then goes to the blower resistor on the box.
