Hello. everyone.
I got 03 mustang converble. You guys may know 6 cd change is pretty bad.
Last month my cd changer dosen't work and I decided change my cd changer to In-dash GPS.

I bought VRVD640G and wire harness.
And today I tried connect wrie between gps unit and wire harness.
All of sudden I figure that out there's a problem with amp wire connect.

Anyway I was have this 6 cd changer unit.
And I have no idea what mach model i had.
There are 8pin,14pin,20pin connector in my car.

Refer the image :
