Technical Specifications

120W Auxiliary Lighting Support

The HJG wiring harness is designed to support auxiliary lighting setups with a combined rated load of up to 120W.

This makes it suitable for compatible fog lights, driving lights and other auxiliary LED lighting systems. Before installation, confirm that the total wattage of the connected lights does not exceed the harness's stated capacity.

Backlit Handlebar Switch

The included backlit switch is designed for convenient operation from the handlebar area. Its illuminated design makes the switch easier to locate in low-light conditions.

The supplied product information also specifies a flashing mode, allowing compatible auxiliary lights to operate in a flashing configuration when selected.

Waterproof Coupler-to-Coupler Design

One of the main advantages of this harness is its coupler-to-coupler connection system.

Instead of requiring extensive wire cutting or splicing, compatible lights can be connected through the supplied couplers. The waterproof connectors are designed to provide a more secure connection for outdoor vehicle applications.

The kit also includes two additional couplers for fog lights or auxiliary lights with open wire ends.

Relay and Fuse Included

The wiring kit includes a relay and fuse, providing the necessary components for integrating compatible auxiliary lighting into the vehicle's electrical circuit.

Always select the correct fuse rating and ensure that the vehicle's electrical system can safely support the connected lighting load.

• Motorcycles
• Cars
• SUVs
• ATVs

It can be used for suitable:

• LED fog lights
