Hey guys, my mother owns a 2010 Acura TL and when she locks the car with her key fob it makes a very cool sounding chirp.
I was wondering if it was possible to make this sound occur when I lock my car instead of the horn audible that is already on my 2004 G35 Coupe.

 

If you hook something that makes the chirp up to body control module's horn relay control wire, you'll get a different sound. It's green with a black stripe and goes to the horn relay from the power control module in the battery box, so it's going to be mixed in with a rather large bundle of wires, not the easiest to get to.
