Plug-n-Play Wiring Harness
- Product Review (submitted on August 15, 2011):
- The Ear Cannon kept blowing the breaker without a relay, so I went for the Plug-n-Play Harness. It made it child's play to hook it up straight from the battery for maximum effect (volume) with the included relay. There was plenty of wire to reach from the horn location back under the seat to the battery so the relay and the fuse could be accessible for service. Polarity for the 2 wire BMW horn harness was the only question-remember the brown wire is the ground on a BMW!
