Review on 🚗 Enhance Your Vehicle's Safety with FARBIN Compact Horn 12V - Loud Waterproof Auto Horn Kit with Relay Harness for Any 12V Vehicles by Rick Ross

Worked most of the day installing this sound system on a tractor only to find the horns were not working. Worked part of the next day double checking that it installed as shown on the instructions page. Revine agreed to send a replacement. When he arrived, the same problems reappeared. We have hired a master mechanic with over 40 years of experience. At first we thought the relay was defective. Installed 2 new relays, nothing helped. The mechanic said it wouldn't work as shown in the diagram and people probably gave high marks just changing the horns. We went the old school just to do the world tour. Something is definitely wrong with the wiring harness.
