The pig tail you refer to on the 72 radio could be the connection used for the
optional casette player. This optional piece of Chyrsler sound equipment was
discussed a couple of weeks ago. The casette player would have mounted on the
floor of the car just under the dash board. The player requires an am/fm radio
with the pig tail. It could be that you have the up graded radio necessary to
install the casette option - or something is just disconnected.
If you are getting sound on the AM setting I would bet there is nothing
disconnected.
I know from prior experience that finding after market radios and dash plates
to mount them is a challenge. Good luck there.
Happy motoring
