Problem Fitting Erisin Radio

I finally got round to fitting my Erisin radio today, as it isn't raining and it's not too cold.

I connected the wires for the steering wheel controls, as well as the wire for the aeriel amplifier, plugged everything in to the radio and the ISO to BMW adapter and reconnected the battery. Turned on the ignition, pressed the on button and........nothing!

ISO to BMW adapter

I checked for power at the plug on the back of the radio. The yellow wire has 12v, the red one does not. So, I checked for power at the car's ISO plug and I have 12v on both wires, leading me to suspect a problem with one of the adapters.

On closer inspection, it appears that one of the adapters is wired incorrectly. The question is, which one? The red wires do not line up when the two adapters are connected together.

Erisin on the left, ISO on the right.

Despite having a set of Durite pin-removal tools, neither of them seem to fit these pins, and I can't even see where the locking tangs are located.

If I can establish which one is wrong, I could hopefully get a replacement. The other alternative is to cut both red wires from their plugs and join them externally.

If anyone can identify which of them is wrong, I would be most grateful.
