what clifford alarm do i have?

So, I bought a used car and the previous owner didn't know what alarm was installed because the owner before that didn't tell him. There's no alarm starter remote either. It's a Clifford, I know that. I need to find out what model I have to get a replacement clicker. I couldn't find the actual module itself to find an RPN number. All I know is that I found a "Clifford Magnetic Resonance Sensor" that looks like this: https://i13.ebayimg.com/05/i/000/f3/e0/2e54_1.JPG What possible Clifford alarm could I have? Is there any other way of finding out which alarm I have?

Find the brain of the alarm.  Find the siren, probably mounted in the engine compartment, follow the wire back into the cabin of the vehicle, and then to the brain of the alarm.  There should be some markings on the brain.
