Factory keyless entry beep / chirp

Hey everyone, looking for what beeps or chirps with the factory keyless entry (2013 double cab). Hoping to interface with aftermarket alarm. Anyone know the pin out? know where it is? thanks in advance for any insight.

 

IIRC, the "horn" for the chirp is mounted on one of the aprons, on the outside of the engine bay under a fender. I think driver's side...

 

right on, i found it just behind the drivers side headlight.... but to my dismay it appears to be more like a speaker then a traditional siren.

anyone know the factory keyless entry module location? thanks

 

I would really be interested in what you find here!

 

i'm trying to figure this set of instructions out to turn off beep when activating keyless dock lock remote.
