Hello, hoping to get the simplest possible explanation for this, as I am not electrically inclined at all. I'm going to be installing a Federal PA300 in my vehicle soon. This unit has the option of using the horn ring switch to activate the air horn.

I want to mount a simple momentary switch (pictured attached) in my dash to activate the airhorn. Can someone explain to me the simplest way to do this? I hooked one up on a Whelen PAP112 once but it was much more straightforward (just two wires from the unit harness connected to the button).

Easy. Connect one switch terminal to the siren's "Horn Ring" wire. Connect the other switch terminal to ground.
