Okay!

The 17-way connector will probably have the following connections. Colours are from my Focus so may not be guaranteed! (pinout attached)

Pin 6 : AVC (Auto Volume Control) a speed signal for volume adjustment - White-with-green-stripe wire
Pins 11 and 12 : remote connections - White-with-black-stripe and brown-with-yellow-stripe wires - these are the 2 you want.

Pins 15 and 17 on mine are also connected. Pin 15 is an output signal from some radios used to provide an enable line to other modules. That wire on my Focus actually lights the reverse light if you power it - how handy! Pin 17 is an airbag sense I believe but I do not know the logic.

For pins 11 and 12 the resistance values are :

Volume down : 53.0 to 55.2 ohm
Volume up : 145.2 - 149.2 ohm
Seek up : 297.6 - 304.8 ohm
Seek down : 556.0 - 568.4 ohm
Mode (end button) : 1026.3 - 1048.1 ohm
Open circuit : 5006.1 - 5107.3 ohm

For completeness sake, and it may save you a few minutes wiring testing, here are the other 2 connectors.

Speaker 8 way (should be sorted by the ISO adaptor)
1 LF+
2 LF-
3 LR+
4 LR-
5 RF+
6 RF-
7 RR+
8 RR-

Power (7 way socket but harness may have 8 or 7-way shells)
1 Battery
2 Lamp return
3 Ignition
4 Illumination
5 Ground
6 Power ground
7 Switched A+ output from radio

Hope that helps?

Nick
