Keyless entry module

Hello, is anyone possibly familiar with the module 100 security system? I don’t think my horn is connected because it doesn’t beep like it should when I unlock and lock my vehicle (like it should if it were connected) does anyone know how to go about connecting the horn to the module/system

 

Not familiar with that system, but the beep for when you lock/unlock is generated by a small cylindrical device under the hood near the driver side firewall. The horn is not part of the lock/unlock sound. See attached diagram, called "TVIP buzzer"

 

Okay, I think I mistyped there with the “beep” I meant more of a “honk” because I have a wire dedicated to the “horn input” or something or that nature. I would like to try and hook it up myself but I just don’t have any clue what I’m looking for. Here’s the input I’m talking about
