I am about to install an alarm on my 2002 trailblazer and already know what alarm I want, but I have a question about the pass lock interfaces. What are the diffecences in these interfaces, and what would you recommend for my car?

If there are any other interfaces that may be better, please let me know.
So far these are the interfaces that I have found. If you have installed an alarm in a car that required one of these interfaces, which one did you chose and why?
The alarm I am getting is a viper 791xv if that helps any.
