:help:

I'm trying to wire up my new Alpine headunit into my mk4 Cupra in place of the standard unit. So far I'm getting NO power to the new HU but that's because I'm not sure which of the Apline wires (yellow or red) goes to which pins on the car's ISO plug.

Does anyone have a wiring diagram of the car end of the HU wiring?

I've got a diagram for the Alpine end of the plugs, but not sure what needs to go where...

Cheers

Swap the wire... so the colours are red to yellow and not red to red

Ric - thanks very much, you're a star :). Actually figured it out myself after finding this diagram posted in a thread within this forum, just after posting my question.

Can't remember exactly who posted it originally, but cheers to whoever did.

Got mine working absolutely fine - such an improvement even just changing the headunit, still running OEM speakers.
