Great loud horn that nobody expects until they get in front and get stunned! I cut factory horn off 2016 Corolla and grounded the 2 hellas. Each horn has 2 terminals which are interchangeable-1 positive and 1 ground. You must splice from factory horn wire and create harness from it. If you do not ground each horn to car it will not work but it is simple to do and definitely gets people's attention. I highly recommend!
