    Ah - you would be describing a full CAN set-up then. (Quadlock connector)

    Full CAN does not have ignition live - instead it has CAN controlled live.

    Only the half CAN vehicles have a black wire on pin 5 (I think) for ignition live. (ISO connector).

    For those reading this - For Full CAN head-units.

    Aftermarket yellow goes to head-unit loom red

    Aftermarket red goes to cigarette lighter plug black

    Wiring is generally very simple, always remember

    Red to Red
    Green to Green
    &
    Blue to Bits

    Aftermarket is different to vauxhall

    As follows: -

    Ignition Live - Vaux = Black, After market = red

    Permanent live- Vaux = red, aftermarket = yellow

    Ground - Vaux = brown, aftermarket = black

    other Vaux colours found in head-units are: -

    Grey/Green, Grey/Black or Grey/Yellow = illumination

    Green = CAN comunications High signal wire - but also see speaker wires below

    White = CAN communications Low signal wire - but also see speaker wires below

    blue/red = calculated road speed signal

    red/white = electric aerial or RF aerial signal amplifier

    speakers are

    yellow and brown/yellow
    white and brown/white
    blue and brown/blue
    green and brown/green

    Vehicle : Opel Vectra GTS

    Trim : Elegance

    Engine : 2.2 DTi 16V

    Apart from the wires colours, live and ignition wires positions are reversed on the ISO connector as compared to standard.

    Half-CAN don't have a real ignition either, it has to be buffered (using transistors for instance), as it doesn't provide enough current to switch on most aftermarket car stereos (nor a Parrot handsfree kit, for instance).

    If you're not buying a specific adaptor loom, you can easily use an NPN transistor and two resistors to switch a 12V relay or just a PNP darlington to provide the necessary signal.

    Another cheap alternative is to use the cigarette lighter +12 (black wire) for the ignition signal. It's very easy to get it from the bottom of the plug, as the connector is actually just made of two ordinary spade connectors : you can find suitable Y derivations anywhere, and it will provide an easy access to a high current and fuse protected contact key switched +12 source for all sorts of uses (gauges, power box, etc.)

    I don't use it for car audio or handfree kit switching, however, because it will switch off as soon as you turn ignition off, while the original radio ignition signal will stay on as long as you keep the key in the ignition switch. This behavior is useful when you want to go on listening to the radio after you turned the car off, but also when talking to someone using the handfree kit...
