It uses a heavy-duty 40A relay and a 30A blade fuse to protect the circuit, and the nylon-sheathed cable resists heat, dust and moisture for long service life. Included are connectors, heat-shrink tubing and a blue-indicator 5-pin rocker switch so you can mount and operate the light conveniently from the cabin.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this harness protect my vehicle’s electrical system?\u003c\/h3\u003e\n\u003cp\u003eThe kit uses a dedicated 40A automotive relay and an inline 30A blade fuse to isolate and safeguard the factory wiring.
