I am interested in putting a cd changer for my Becker Grand Prix 1432 2 piece system,I have located the components in the trunk on the right side but unable to find the so-called connector to the cd-changer.

The only possible connection that I see is an unconnected 6 pin round connection on the amplifier unit, could this be it ? and what cd-changers would fit the head unit controls ?
