I've had a look at the two connectors in the boot, and I haven't worked out what they are yet.

One has three pins, the other six.

By a process of deduction, there has to be at least these things:

1. GND
2. +12V
3. Audio Ground (although there could be a left ground and right ground)
4. Left Audio
5. Right Audio
Other pins: Control e.g. disk 1-6, FF, REW.

The first thing I need to know is how to tell the radio that there is a CD player attached, so the MODE button will switch to CD.

I hope its as simple as connecting one of the control pins to GND or +12V, although with much of the wiring being like a computer "bus" - it could be some hopelessly complex sequence of pulses.

I'm not willing to start probing around with these until I know which pin is which!

Does anyone have any ideas how I would find this out. For example, if someone owns an autochanger, does it have a pinout diagram in the manual?
