Product FAQ

Will this harness work with my factory lighting and aftermarket LEDs at the same time?
Yes. This harness is a dedicated auxiliary circuit—it doesn't interfere with factory lighting. Run factory lights on stock wiring and aftermarket lights through the relay harness.
Do I need to remove trim panels or drill holes to install this?
No. The harness connects directly to battery terminals and grounds to the frame. No cutting, drilling, or trim removal is necessary.
What vehicles does this fit?
Fits all generations of Toyota Tacoma (1st–6th gen), Tundra (all 200 and 250-series), 4Runner, Sequoia, Land Cruiser, and FJ Cruiser. Use the fitment verifier to confirm your exact model year.
