Hi everyone. I just purchased a vehicle with its alarm already installed, and it is activated from the remote control, but when opening the doors or making a movement inside the vehicle (volumetric) it does not fire. I already checked the switc and the volumetric ... but I don't know if everything will be well connected since I don't have the schematic. That is why I wanted to know if someone can give me the programming manual and the connection echematics to be able to check it. The alarm in question is a PST model FX270US, check here in the forum but the link was down. Greetings to all. Cristian
