Pin Installation Foreign Radio 451

Good evening! I hope you can help me. I doubt slowly. For my “smurf” 😉 I have bought the Kenwood KDC-BT43U. In addition, I have ordered an aperture from the bay, which was delivered with an adapter. Now I have only now learned that a “Plug & Play” is unfortunately not possible. I have been looking for more than 1 hour, how to move the pins (and whether this is possible with the 2nd adapters at all or I have to get a new one). Unfortunately I have to the instructions of Möma did not help:-( I probably have two left hands for it. The adapter that came with the radio has only 4 cables on the right. The one from the aperture has 5. I upload some photos, maybe one of you can see something and help me.
