The original plug that connects the battery pack to the radio had 3 wires:
Green = Negative for the radio.
Black = + 12 V for the radio power and shared common (negative) for the dial light battery... connects to chassis ground.
Brown= + 1.5 V for the dial lights.
I suspect that the extra wire is the brown wire, likely the dial lights have been connected internally through a resistor, the 12 V nicad pack powers both. (LED mod, perhaps?).
