Hello everyone. I bought scion security and piezo buzzer from my dealer. I installed Scion Security, and i want to install piezo buzzer somehow to make sounds when i lock and unlock the car. my car is xB. Does anyone have any idea to connect the buzzer to this car? As you know, Lexus and some toyota cars make piezo chirps when it's locked and unlocked... I want that sound!! the piezo buzzer i got from toyota has red and black cable.
