Depends on if your going to put a upgrade alarm with remote start or just add it to your stock alarm... I have had remote start on a few of my cars and did it both ways .. If you have a good stereo shop they should be able to give you all the info you need ...
One big thing wrong with using the remote start is you usually kill your starter after awhile and some electric signals can start your car at least I have experinced this before ,.. unusal .. but scary at the same time .. Good luck with your adventure .. and have a great new year ..
