Found the cable - it was nicely tucked away but had a sticker saying "only to be used with Phanteks LED". Connected it all and works perfectly with the. Button on the case.
This is what it looks like all built:
Have packed it away as I need to sort out my desk and everything else. Will send more pics once all is connected up again.
