Rfroad Lighting 12V Wiring Harness 2-Lead Kit — 40A Relay, 30A Fuse, Blue Rocker Switch, 11.4ft Nylon

This wiring harness is built to make adding LED light bars, fog lights, pods or rock lights to trucks, UTVs, ATVs and boats fast and dependable. The two-lead design supports up to a 300W combined load and includes heavy-duty protection components so you won’t have to splice together parts or improvise a safe circuit. With 11.4 feet of nylon-sheathed cable, insulated connectors and heat-shrink tubing, the kit gives everything needed to mount lights and complete a professional electrical connection.

How does this harness keep my lights and vehicle safe?

The kit uses a combination of a 40A power relay and a 30A blade fuse to guard the circuit against overcurrent and short circuits, reducing fire and wiring damage risk. The dual protection approach isolates the switch from high current while the inline fuse provides a sacrificial element if something goes wrong.

• 40A relay handles high inrush and running current away from the switch
• 30A blade fuse protects wiring from overloads and short circuits
• Nylon jacket offers higher heat resistance and abrasion protection than PVC
• Fully insulated male/female connectors and heat-shrink tubes secure joints

Will this harness fit my light bar or fog lights?

The two-lead harness is designed for universal fitment across most 12V lighting products, from compact LED pods to larger 52" light bars. It supports a combined maximum load capacity up to 300W, so check your light pair's total wattage before installation.

• Compatible with 2" to 52" LED light bars, pods, fog lights and rock lights
• Works on any 12V vehicle electrical system (cars, trucks, UTVs, ATVs, boats)
• 11.4 ft wiring run provides flexible mounting locations and routing options
• Includes universal connectors for straightforward hook-up to most fixtures

How easy is the kit to install and operate?

The harness arrives ready to wire with a pre-wired rocker switch, relay, inline fuse and fully insulated connectors. The 5-pin on/off rocker switch has a blue indicator lamp for night visibility and is rated for long life, simplifying control without additional relays or modules.

• Pre-wired components reduce installation time and wiring errors
• Rocker switch rated for over 10,000 presses with blue indicator light
• Heat-shrink tubes and rubber fuse cap improve durability and weather resistance
• Clear color-coded leads and connectors make wiring intuitive

What materials and extras are included in the package?

The harness uses a tougher nylon jacket instead of traditional PVC, improving resistance to heat, oils and abrasion. The package bundles everything needed for a clean install so you won’t need extra parts in most setups.

• Nylon-jacketed 11.4 ft 2-lead harness for durability and heat tolerance
• 40A relay, 30A inline blade fuse with rubber cap, and a 5-pin rocker switch
• Fully insulated male and female connectors plus heat-shrink tubing
• Manufacturer support and 24-hour after-sale service contact
