Honda GL1800 Ground Loop (Noise) Isolator

The Ground Loop Isolator, from Electrical Connection, is designed to remove hiss and alternator whine from the audio signal. Plugs into the factory wiring harness AUX connector, under the left-hand fairing pocket; no adapters are required. This is just the ticket to reduce to totally eliminate that annoying noise in your bike's audio system, when connecting a bike-powered satellite radio, iPod or MP3 player to the AUX plug in the left fairing pocket.
