Universal Wiring Harnesses

Overview
Reviews

Choose the perfect harness for your setup with options to control one light, two lights, or even four lights! The brass grommets on the positive and negative terminals make connecting to the battery or accessory post a snap. Each harness comes with an inline fuse, a relay, and a switch. The switches can be easily swapped out with a rocker switch, check out our rocker switch options here.

Generally, our lights have a DT connector unless it is one of our very high-power lightbars, in which case, the listing will say it uses an ATP connector.

We also have wiring harness extensions if you're just looking to add some extra length to your harness. If you only need a small replacement part, check out our connector parts or replacement fuses/relays.
