hmmm

Sorry to revive an old thread but has anybody else done this? and to the people that have done it have you had any problems with any electrical components on your car?

I went and had a glass and shock sensor installed on my factory alarm took 2 hrs.
It's doable

They now make a direct plug and play kit for select nissans allowing aftermarket alarms and aftermarket remote starts. Usually these are through Direct (viper) and usually take about an hour by the time you install and program everything to do.

Is there an obd that you can plug in that sends sms messages to a preprogrammed # when car alarm goes off?
