Wiring Buzzer into Remote Start

Im wanting to wire a buzzer into my remote start so that I know when my doors are locked and unlocked. My parking lights blink twice when unlocked and once when locked so I would prefer to have the buzzer work the same way. Wired them into the parking light output out of the remote starter module and of course it stays on when my parking lights are turned on .

Any gurus know what I'm doing wrong ?!

Its a Python 1401 Remote Start in case anybody wants to look at a wiring diagram. figured Id try to wire it to the door locks next but was hoping someone could before I do that

 

Went ahead and just traced down the wiring diagram and wired it into the "lights on" warning buzzer.
