Just removed an after market radio to go back to a stock gm 6disc. The stock radio has two plugs and can only find one in the harness. Anyone know what the second plug is for?

From this thread...

The black 12-pin connector on the rear of the factory head unit is for an external CD changer that is not installed in the SSR.
