Aerial booster power cable - where does it go?

[Pipes]

Hi all,

I've just replaced the HU in my Leon with a Kenwood one. I bought one of those aerial boosters after doing my research on here saying that I needed one.
I've put that into the HU and then plugged the aerial into the booster, but I have the small power cable coming off the booster too. Where does that go?

According to the Kenwood manual I have a cable which is part of the ISO lead which is Blue/White and is for "Power control / Motor antenna control wire". It doesn't say what voltage it is.
Do I use that?

If no, does anyone know where I connect this thing up?
It looks just like this:

yeah that will be fine to use it on that wire from the H/U, its switched so only comes on when the h/u is on. It will be 12v thats what the aerial adaptor needs.
