Well, I just got info on finally what is to happen! Apparently the Nissan Xterra security system doesn't have a transitor (and I knew that because I searched). The reason I had my doubt was because the guy at Omega told me that I would need to get a key for the remote car starter to turn on my car. Long story short, tomorrow I will be calling him, and he will ship me a plain and simple add-on remote starter (100$). He will also send me directions on how to wire it, which I'm sure I know how to do. It's a two or single push button. So in other words I can wire the system so that I can either press 1 time or 2 times on any button (lock, unlock, or panic) and the engine will start. I told Shockin about it, and he seems optimistic, but he's gonna buy it cheaper offa another site (probably 80 with shipping). Anyway, the actual Add-on remote starter is a Omega RS-4LX. So if anybody in the future decides that they want to install a remote starter that works with the factory buttons and system, then e-mail me. I will be able to not only provide directions, but tell you if the system itself is good. If anybody has any questions just ask. I personally plan on making the engine start by tapin the panic button once, which makes sense cause if somebody is messing with my car, then not only will the panic go off, but the engine will start. It'd scare the crap outta anybody if some car started randomly with nobody inside! I don't know if the system has a engine off option, though I'm sure it does. I'll probably make the engine off option a 2 button lock.

So if anybody has any questions then feel free to ask!
