    I've just purchased a used cd changer for my 2003 E270cdi with fan & fitting screws included.
    The new fibre optic & power harness is on order, (expected any day)
    The head unit is APS 50 audio.

    I appreciate that 2 of the wires are positive & negative with the 3rd being the wake up, Im just unsure which ones are which.
    The wire colours from the cdc are Red, Black & yellow, any help as to the configuration would be greatly appreciated.

    The proper power harness makes it obvious. There is a brown with an earth lug on it, a red/something with a fuse block on it that goes into fusebox at end of dashboard, and a pink wakeup wire with a connector that clips into the wakeup distributor block in passenger footwell wiring duct

    Thanks Richard,
    Unfortunately I missed out on one of your harnesses, online store showing as out of stock.
    The one I've had to get all three cables are the same colour, with bare ends, hence why I needed to identify the three colours from the cdc.
    I have since been informed that:

    Red = Positive
    Black = Earth
    Yellow = Wakeup
