1965 valiant heater wiring question: what's this wire?

[J Glenn]

This first picture is looking into the (removed) glove box at a green wire and a brown wire. My question is: what is the (2nd) brown wire ("B"). The green and brown wires ("A") are from the heater control switch. The 2nd green wire ("C") and the 2nd brown wire ("B") seem to feed to the blower motor. The wiring drigram doesn't really show this. C4 (brown) and C5 (green) seem to go to the 'blower motor resistor'.

Why do I ask? Because the 2nd brown wire ("B") is grounded. Not sure if that's right because I don't see that in the schematic.

Ideas?

That is correct. It's the ground wire for the blower motor.

Runs behind glove box then behind kick panel where it is grounded with a screw.

Do you realize,
that you are probably only the second guy in history,
who ever took the front of that box off,
without first taking the entire box down?
Just wait till you go to put it back on,..........................................................lol
