I have a smaller aftermarket air horn installed on my ‘02. I wired it to a small push button which I installed in one of the blank spots below the OnStar controls. The horn works just fine, but it’s small so by itself it doesn’t quite have the effect I was looking for. However, if I activate the air horn simultaneously with the factory horn it sounds pretty decent.
My question is this… shouldn’t I be able to locate the two wires for the factory horn and tie in the two wires running to my push button for the air horn and be able to sound both horns at the same time by pressing the factory horn / steering wheel?
