Hey there! I recently installed an airhorn on my 6 using the relay they provided. First off, it's essential to consult the vehicle's manual or wiring diagram for specific wire colors and locations. In my case, I was able to locate the horn wire under the hood, close to the fuse box. The color might vary depending on the model year, but for my year, it was a wire https://bosshorn.com .

You should be able to tap into this without going all the way to the steering wheel, which saves a lot of hassle. Ensure you're connecting to the right wire, though – a test light or multimeter can be useful here. Also, ensure that your connections are solid and insulated properly to prevent any potential electrical issues.

On a side note, when I was mounting the air horn itself, I used my dewalt drill air horn, and it worked like a charm! The power and precision it offered made the installation process a lot smoother. Hope this helps, and let me know if you have any other questions!
