Consider this harness when installing your LED Light Bar or any other auxiliary lighting. It comes completely assembled and is ready to connect to your vehicle with no drama.
This harness is constructed with high capacity waterproof connectors, built especially for high wattage (140 watt+) LED light bars. Sure, you could make it yourself, but considering you get a 20' long (10' from the battery to the switch and another 10' from the battery to the light) fused, relay installed and a push button on-off switch, why would you bother?
Also included are "Duetsch" wiring connectors for a vibration & waterproof connection at the LED Light bar or any auxiliary lighting.
