Chrysler Repair: Stereo wiring for 2000 Chrysler Concorde, chrysler concorde, 2000 chrysler concorde

Question
Hi,
I got a factory installed stereo in my car and Im puzzled with one connection to the upper right corner of the rear of my stereo. The upper left corner has the Antenna, but the upper right corner has a 2-pin connection which I amnt sure of. would you be able to answer that? In all, I got a GND at the center of the stereo connected with a nut, 2 7-pin harness wire connections, 1 8-pin CD changer connection, the  antenna connection and then the 2-pin connection in question?

Answer
Hi Ajith,
That one, if it black and has a single yellow/violet wire, is the digital data connection (PCI bus) wire. I am not that familiar with what it does, other than maybe serve for remote control of the radio from the steering column?, but that is what it is.
