Review on 🔌 Nilight NI-WA 06 LED Light Bar Wiring Harness Kit: 2 Leads, 12V On/Off Switch, Power Relay & Blade Fuse - Off Road Lights, LED Work Light with 2 Years Warranty by Brad Lovro

Great Deal on Quality High Beam Headlight Wiring Harness. A few things: Instructions could be better. Note that the switch's hot (+) wire must be connected to your vehicle's optional switchable wire. I used a mini fuse adapter, added a circuit and tapped it that way. If you also connect the switch directly to the battery, the light will turn on and off even without a key in the ignition. For safety and protection reasons, it is better to connect the batteries with the cable provided. The minus on the switch just needs to be connected to the nearest ground - not necessarily back through the firewall to the battery minus. I used the floor from the stereo. I didn't like the big switch that had to drill a huge hole in the dash, so I replaced it with a smaller switch with an LED. Easy to connect - it took me longer to securely install my high beam headlights.
