Review on Pit Bull CHIH310 12-Volt 🚂 Air Horn Upgrade for Optimal Performance by Roel Lebron

Bought because it was cheap. Was a bit concerned about the lack of information these horns had on the internet but decided to give it a try. The horns aren't the loudest, but they will definitely help. The instructions are terrible. Me, my mechanic and even two alarm technicians couldn't get it to work as instructed. Eventually the alarm tech routed the cables the way he saw fit and BOOM, they worked great. Update: 05/15/2017 Due to the year of use of this item I have to replace it. The compressor has failed. Decided to buy again because of the price. I checked the wiring and took it to a technician who confirmed that the compressor had stopped working. Hope it lasts longer this time.
