Control Your Baja Designs Lights From the Factory Switches
The Baja Designs Upfitter Harness is the clean solution for 2025+ 4Runner owners who want their ditch lights, reverse lights, or grille lights controlled from the factory OEM upfitter switches — not a toggle switch zip-tied to the dash. This plug-and-play harness connects directly to the factory auxiliary switch wiring, letting you run up to four Baja Designs lighting kits through the OEM switch panel for a fully integrated, factory-appearance install.
Whether you're running a Squadron Pro A-pillar kit, an S2 reverse kit, or a grille light replacement setup, this harness eliminates the need for aftermarket switches and keeps everything organized and reliable. Designed specifically for the 2025+ 4Runner's upfitter switch system — no universal adapters, no wiring guesswork.

FAQ
What are OEM upfitter switches?
The 2025+ 4Runner includes a set of factory-wired auxiliary switches in the cabin (typically on the overhead console or lower dash panel depending on trim). These are pre-wired circuits designed for exactly this purpose — running aftermarket accessories through factory-quality switched power without additional wiring.
Does this work with the new Squadron 2.0 Pro kits?
Yes — the 44-0011 Squadron 2.0 Pro A-pillar kit is compatible with this harness.
Do I need this if my kit already came with a toggle switch?
No — the toggle switch harness works on its own. This upfitter harness is for owners who want to eliminate the toggle and control everything through the factory switch panel instead.
How many kits can I run on one harness?
Up to 4 Baja Designs lighting kits per harness. The kit includes 2 harnesses.
