Second Horn Option, 1999 Suburban?

Hi All,

When I had my grill off I realized that I have a plug for a second horn. It takes power from the primary horn

Art, you maybe talking about the outside temp probe located under horn that is already there, it's black and has the probe sticking out the side of the plug. Your second horn should be mounted in front of the pass side battery......
It's below the center horn behind the center of the grill. I didn't notice anything sticking out of the side but it plugged into a black plastic holder and is attached to the radiator support. Based on your description that's probably what it is.

Thanks!
Art.
