Car Alarms: Car Alarm Question, vw jetta, alarm interface

Question
Hi I was browsing around your website and i noticed a few alarms I liked such as the 2way paging ones but the issue i am having is that i have a 2005 Vw Jetta (old body style aka MKIV) and i see that they have items such as the XK01 alarm interface, a Vw Door lock interface, what do i need to get an alarm to work flawlessly with my vehicle?

Answer
Well, troublesome electronics when dealing with
after market alarms. Doable, but tedious.
The underpanels are built to be left
undisturbed, so removing them to interface
anything is a chore. Then
you will have a difficult light flashing
system. This will require diode isolating and
relay/resistoring the parking light wire in this car.
Hard.

Other then that, your choice of system, along with the
IM01-XK01 Module would make a pretty complete security
choice to interface.

I have the notes on it, and they will be
provided upon purchase for the project.
