now that ive put all this sound system stuff in my car, ive decided that im upgrading my alarm. I like to do work my self so i kno its done right. Im going to buy a Viper 2-way alarm without remote start, now how hard would this be to put in? will i be able to use the factory alarm speaker? can i still use the LED in the door as well? i don't want drill any new holes.

Ive searched but can't find EXACTLY what im looking for

 

your gonna have to disable the factory alarm..and rewire to use the LED...if your adding an alarm and not a shock sensor only..your stock alarm is basically useless...use the siren and LED that comes with the Viper
