That alarm is hardly a plug and play system. With the remote start it is a major job. Also, the wiring on those two cars is not exactly the same. You can get some of the wiring info here:

I can pull up some other diagrams if you want more and can't find it. As a dealer I have access to some other diagrams. I am not sure about that model but most of the DEI alarms have the wiring listed on the brain of the alarm, maybe you'll get lucky. You can get the owners manual at
http://www.directed.com but not the install manual. The hood switch you should be able to buy at a stereo shop or many automotive stores like Checker, Autozone, or Pep Boys. I stock them but it would cost more for freight than the switch is worth.
If your car is a manual transmission be carefull with that remote start.
