Review on 🔳 HS-2 Wolo Horn Button Switch Kit by Chris Brazington

works great. That's all you need to bypass your horn. Look at the back of the box - use the car's built-in relay and fuse. For example see photos: I cut the wire after finding the right length. A wire goes to a relay in the engine fuse box. The other I wrapped around a nice stud on the side panel fuse box for grounding - this is important if you have bad ground, the horn won't work! Connections. I recommend stripping all ends for a good connection. Finally screw it into your dashboard!
