^^^^what this guy saidthrow a killswitch in there on the fuel pump and do security mods first...
use this link: http://causeforalarm.thecarthing.com/version6/stealth_alarm/ek_civic/index.html
to update your alarm because it has some really common flaws that can make it quite useless to protect your car from a thief.
First: Rerun your hood release cable through the engine bay, because the thief can easily reach under your driver's side fender and cut the cable, and if you don't have a hood pin connected to the alarm, the thief can just open your hood, cut the siren cables, making your alarm mute...
An alternative is installing a hood pin that will trigger the alarm when the hood is opened.
Second: Hide the siren, maybe install a secondary in case the thief can find the first one.
Third: Install battery backup for your alarm, in case they cut the power, your alarm will still function...

But this is only my 2c of advice.
Good luck with the build bro. Keep this thread up to date.
