Installing Polini CDI on a Honda Zoomer 4T 50cc 2006

I’m hesitating to order a cdi polini for my Zoomer.  After some Googeling i found out that installation is not so easy as it should be (plug and play ?)
My zoomer has a tremendous bunch of cables, everything is with plugs…so i’m a litte bit afraid to cut in these cables…
Who has some experience in this …and does the cdi really unlock the max. rev from 8000 to 12.000 rpm ?
A cabling/stallation diagram of the cdi should help.
I changed already the vario, so it runs now 60km/h flat and 65 downhill, but some more revs should help.
