late 6n or 6n2 immobiliser plug

I need the large plug for the immobiliser box (the one that connects it to the cars loom), I only need the plug and about 4" of the wires coming from it. It's for a late 6n but looking at Google it seems the 6n2 uses the same immobiliser box and plug

Picture stolen from Google to show what I'm on about, it's the bigger of the two plugs
