over a year ago i put a quick release and knockoff bride wheel in the car no horn no biggy,but now i kinda think it would be nice. since the hot wire is ran through the srs harness. where do i splice in to the factory hot wire or what do other ppl do?i'm sure the answer is so easy and thats why i'm over looking it.

 

I bought a louder aftermarket horn and mounted a horn button on the dash in that spot to the left of the steering wheel...right where the cruise control button used to be.
