Radio Wire and/or Connector

[vespaholic]

My newly acquired 1979 C20 is missing its factory radio.
Fortunately, the PO did not cut the dash.
Unfortunately, I can not find any of the original wires at all.
Nothing is cut and hanging down; nothing.
No speaker wires either.

The truck came from the factory with an AM ONLY Radio.

I pulled up the carpet and found these (PICTURE #1)

The one on the right I believe is for the seatbelt buzzer.
So, I will not reconnect that.

The connector in the second and third pictures is the wire in question.
It was tucked behind the wiring harness as if to get it out of the way.

PINK with BLACK STRIPE = Power with ignition switch on. No power with ignition switch off.

ORANGE = Nothing Under any condition I can think of.
Ignition or or off, nothing
Lights on or off nothing.
Accessory position, nothing.

Is this the radio connector/wire for an AM radio?

If not, what is it?

Anyone have a pic of where the radio would connect to the harness?

Thanks!!!
