It's been a year since I purchased my 46. The previous owner called last weekend and told me he'd been cleaning the shed and had come across a set of horns for my truck.

What is the easiest way to check if they work?

Also, could someone explain how I should wire these?

I know I'm going to have to use an aux. horn button, but could it be as simple as power and ground through the button?

Thanks in advance for your assistance.
