JVC KD-S640 pinout needed

I have a JVC KD-S640 CD player I would like to use but the rear connector is missing and there is no pinout info on the unit, my thought was to solder wires directly to the pins making my own pigtail, anybody have the pinout info they could share? thanx

CD's are being ejected without play (JVC KD-s640)

Take a torch and see if there are any foreign objects in the loading compartment. Children are know to insert for coins to just about anything they can squeeze through the ****.
Then try removing the system from the dash and open the top lid. see if you can clean the lens from a small cutout on the loading mechanism using a cotton ear bud. Do it in good light because the lens ( looks like a fish eye ) can oly been seen at an angle through the cutout.

Cd's won't play

Its dirty, try a disc cleaner, (brushes not solution) and if that does not work, its time to replace, (unless the radio is all ya want).
ALSO- if you are trying to play burnt discs, (cd-r, mp3 discs etc) than that could be the issue as not all indash cd players support non store bought cds

I want to wire the kd-s640 to my boat. I need to know what wire by color (except black ground) goes where. Thanks.

Usually it's....

black = ground
red = switched battery power
yellow = constant batery power (for clock...etc)
orange = illumination
blue = amplifier turn on or accessory (electric antenna, amps etc)

green/white/purple/grey are speaker wires.

Most versions of the JVC KD-S575 uses the 16pin block connector as shown below. It is available at the JVC Accessory Store.
Below image shows the pin's alphanumeric designation.
Color coding and where connected is shown below.
A2 Brown - cellular phone/mute
A4 Yellow - Always on B+12 (such as the battery's positive terminal)
A5 Blue/White - Power Antenna
A7 Red - Accessory or switched +12VDC
A8 Black - Chassis/Ground/GND

B1 Purple - Right Rear +
B2 Purple/Black - Right Rear -
B3 Gray - Right Front +
B4 Gray/Black - Right Front -
B5 White - Left Front +
B6 White/Black - left Front -
B7 Green - Left Rear +

Error 10 message on display screen

Same issue but pressing Power and SEL would not reset unit. Found solution. Once again disconnected the car battery. Removed the face unit from the radio base and then reconnected the battery. Replacing the face unit AFTER the power was re-established solved the issue. (Probably pulling the radio fuse rather than toying with the battery connection would have done the same thing.)
