Aftermarket horn with button

[jabolen]

New to the site! Anybody have any creative spots for horn button? I have 90's steering wheel that I don't want to dig into. Just want to place button somewhere convenient. Any ideas or other pics of location? Bought cheap button and I am apparently to ignorant to wire the simple button. Bought a Dorman 85929 and can't figure out how to make it work. Horn is wired and feed is in cab with 16Gauge wire but can't figure out button. Touch hot wire to metal and horn sounds but can't figure our how to wire button? Yes I am an idiot!
