k12 aftermarket radio adaptor?

[747_727]

Im trying to fit an aftermarket radio in my wifes 06 reg micra but I cant seem to find the correct adaptor lead anywhere for it.
Does anyone know what lead I need? Its for the basic 2 speaker radio.
Picture below of back of radio. Sorry for bad picture but I didnt unplug the radio as I havent got the code for it!

That looks like standard ISO - means no adapter needed if you buy a new one with ISO .

Thats great mate.
I was getting confused by the plug above it which I thought was for the speakers but I since found out its for something else. Any idea what it does? The car hasnt got steering remote or anything else.

the lead controls everything for the radio, power, earth, left and right, front and back speakers (Y)
