I've been happy with the OEM alarm system since I've had the car. Recently, IASCA (car audio competition organization) added alarm systems with battery backup to the rules/points. I've been looking into Compustar www.compustar.com - but want to hear from those that have succuessfully integrated an aftermarket alarm.

Does anyone have a B5 wiring diagram I can look at?
What alarm system did you use? How difficult was the installation?
Are there any tips/tricks you can share with me?

I've searched this forum and found some disturbing posts about compatibility issues, and want to make sure I get it right....

THANKS!
Matt
