    What colour is s/w +12v for H/U?

    Ive a mk4 astra cdti van (got a jvc headunit in it) and im pitting a wiring kit in for an amp.

    I know normally switched +12v is normally BLACK, but the std h/u plug has no black wires, and my multimeter seems to be wonky (im getting 3 12v wires, none switched though..)

    Ive fitted amp's to 3 mk4's now, and its always been simple.

    I know i could use the switched supply from the cig lighter, but would rather use the appropriate one for the headunit.

    Black on the cars loom is switched live.

    Cant see why its not unless the fuse has blown.
    The truth is always the truth even if you haven't realised it yet...

    I suspected any switched +12v for the h/u was done when the key is removed from the ignition....

    So thats what it was, vauxhall colour was a thin red wire, JVC colour was yellow, so all sorted
