Looking at the deck, from the back.
Right channel is pin2
Left channel is pin3
Ground is pin8
Control is pin5
Just an update on this if someone gets a chance to answer. I tested the DIN socket on my headunit last night - with the intention to try applying a 6v control input to pin5 to tell it a changer was attached. However, pin5 has 12v present on it. When the unit was playing the following voltages were present
pin1 5v
pin2 5v
pin3 0v
pin4 5v
pin5 12v
pin6 0v
pin7 12v
I presume from this, I can't use pin5 as a control?
Thanks,ben
