My Dad has successfully fitted one to my mum's 2006 brera. Some wiring was involved but it was relatively straight forward. No canbus issues.
There are 3 wires that go to the switch in the glove box. One is an earth, one is a feed for the light and one operates the release. Tap in to the release wire and feed it through the car and into the boot lid down to the badge. The other wire from the badge is just an earth, so that's easy enough to sort.
The outer skin of the bootlid is cut to accept the badge but you'll have to cut the inner skin, using the outer skin as a guide to get the badge to fit.
The most difficult part of the job is feeding the wire through the rubber wire conduit into the boot apparently.
My Dad check that the boot release button in the glove box didn't work with the car locked, it doesn't but being a different country I'd suggest you check this first.
