Audio Systems: Aiwa CDC-X227, aiwa cdc, cable side

Question
I have an Aiwa CDC-X227 and the harness that I have that fits into the stereo may or may not be the original one. How can I find out what the configuration of the 16 pins is? Thanks!

Answer
All Awia use ISO DIN plugs, 8 for speakers and an 8 pin for power as below.

DIN connections  are.
Speakers

Right rear -,  right front -,   left front -,  left rear-,
Right rear +, Right front +, left front +, left rear +

Power block viewed from cable side

Phone mute (white),/   n/c, /      ariel & amp (blue), /ignition (red)

N/c, / 12vlive, (yellow or orange), / lights, (various colours),/ negative (black)

The third, usually top, block is for accessories such as cd changers
