I'm replacing the factory horn with a PIAA dual tone horn and i'm a little lost (very little experience with wiring). Do I need to build a wiring harness to do the installation? I couldn't find a walk thru in search. Thanks all.

No special harness required. The most you may need to do is crimp on some new connectors, if the PIAA horn doesn’t have spades (like the factory horn does). The circuit is already powered through a relay, so no wiring changes are required

It comes with two wires, crimp on one side spade on the other. So.... How do I wire it? lol
The horn will need both +12V and a ground. The factory horns grounded out to the body, so you may have to make ground wires for the PIAA, if it has a specific terminal for it.
The factory wiring supplies +12V only.
