Without it in front of me and doing it I can not think of which blanks the pins go to. Just line it up with the factory one and locate the factory wires that are needed. That would be the way I could recommend

hey big, i have an extra metra harness and was going to pull it apart to get the wires and pins to just add them to the harness i am using to make it plug and play. i have the bose non navi and am using the harness to retain stock bose system. could you confirm which hole i add these to please.
