Plug-in-ready, relay-equipped harness for adding auxiliary lights to the Moto Guzzi V100 Mandello

This harness runs power directly from the battery, through a fuse, to a relay. Light operation is controlled by the original Guzzi handlebar switch. Easily add aftermarket lights to the V100 Mandello. Plugs directly into the existing OEM Moto Guzzi wiring harness. Operates with the OEM handlebar switch. Extra long wire leads to support various routing and light placement options (2000 mm). Sealed relay. Includes terminals to make connections to auxiliary spot lights, LED lights, etc.
