These switches are 1.75" tall and 1" wide and come in multiple laser engravings.

    Wiring Harness Pigtails

    These pigtails are for doing your own wiring and have raw wires on one side and a connector on the other side. The length of these varies but they are usually 3 to 6 inches long. If you are looking to extend your wiring harness and don't need the connector parts, we have wiring harness extensions or complete wiring harnesses available.

    Wiring Extensions & Splitters

    Add extra length to your LED light bar wiring harness with our wiring extensions, or use a splitter to turn 1 DT connection into 2! If buying by the foot, enter the footage needed and then hit add to cart.

    Connector Parts

    These parts are for when you are doing your own wiring or fixes. These go on the end of the raw wires and include the connectors and necessary parts (no wiring included). We also have full wiring harnesses, wiring harness extensions, wiring harness pigtails, and replacement fuses & relays available.

    Wiring Harness Relays & Fuses

    If you're a do it yourself person like many of our customers, you might want to replace harness parts yourself. These fuses and relays are simple to replace on any harness. We also have replacement connector parts or wiring pigtails if you just need the connector with a short bit of wire. But of course, if you're the type of person that just wants to plug it in and go, we always have our full wiring harnessesthat make installation a breeze!

    Relay Holders

    Relay holders are used to help organize your relays under the hood. One relay holder holds up to 3 relays one per prong. Choose between a universal mount with M8 rivet nuts (may require holes to be drilled) or bolt-on options for the 4Runner and Tacoma with bolts to fit the pre-drilled nuts in the engine compartment.
