Is there an easy way to tell if my Camry Hybrid has the factory alarm installed?

I'm working on a project to install an aftermarket alarm and remote starter system and one of the wires to connect is a hood pin switch wire, and through my research on here at toyotanation I've read that if your car has the factory alarm that you already have a factory pin switch installed and you can tap into that wire underneath the dash by the OBDII connector. Problem is, I looked on my car by the hood switch and I didn't see any electrical wires. So now I'm thinking I don't have the factory alarm.

If I roll the windows halfway down and lock the doors with my smart key fob, if I reach in the window and open the door without the horn honking (and the smart key is not in the immediate vicinity), does that mean I don't have the factory alarm system?

 

As far as I know, all the TCH's have a "Factory Alarm".

The hood is not part of the system. There is no "hood pin switch".

 

I know that's what I thought too. Can they be disabled or something? I couldn't find a setting in techstream to enable it. Because when I tested mine nothing happened when I opened the door by reaching through the window.
