The absolute easiest DIY I found on this (just did this to my wife's vert) is this one. Best instructions/images w/guides that I found. The best part is that it also includes some nice cleavage.


Really excellent stuff like this:

And this is also very useful:

Just skip the motion sensor section for a vert.

My car has the blinking lights at lock/unlock but the alarm is NOT enabled after installing siren and tilt sensor in the trunk. So don't assume that if you have the blinky lights when lock/unlock that you won't need to get the alarm coded to be enabled.

I had to buy the bolt for the siren (bought it used and it wasn't included) - in case anyone needs that info it is M6x16.
