Plus your car is already completely wired for it. Some newer models aren't. You will get the deterent effect immediately on install even if DIY. The clown nose on your mirror will blink. It will blink and error code, but thieves don't know that. Once you get it coded (dealer charged me $100, indy should be less) it will blink the correct pattern and functions as designed. It works great and I have never had a false alarm. If it goes off, someone is tampering with your car or you locked the dog in there. Learned that from experience.
