Product FAQ

Will this relay work with my factory Toyota switch panel?
Yes, if your truck has a ground-switched 8-gang panel. This relay is designed specifically for OEM Toyota switch architecture. Refer to the fitment guide or contact support to confirm your panel type before ordering.
Do I need professional installation?
No. This is a bolt-on relay harness with color-coded terminals. If you're comfortable connecting basic wiring and soldering or crimping terminals, you can handle this installation. If you're unsure about electrical integration, professional installation is recommended.
What if my accessory uses a different switching logic than my panel?
That's exactly what this relay solves. It converts ground-switched signals to hot-switched output (and vice versa), eliminating the need for custom harnesses or dual-wiring solutions.

Finally a shop that actually knows Toyotas. No guesswork, no wrong parts.
