Additional P420 + 8 SFF drive cage in ML350 G8, power cable?!

[MartinM9700]

I'm installing a P420 and an additional drive cage in our server, but I cant seem to find an extra power cable/connector for the cage. I can only see one, which is already plugged in to the original drive cage. Do I have to unmount the "other" side of the case (the one that needs tools, and dont just click-off) to find it, or ...? My server is equipped with dual 460W PSU's, if this helps answering the question :-)

I might have answered my own question: Is the power connecter on the motherboard right beneath the fan cage?! It seems like it when reading the manual (the server is not in my hands at the moment, so can't check it).
