The Upfitter Harness connects Baja Designs light kits to the factory auxiliary switches on this vehicle, so the lights run from the dash controls the vehicle already has. It contains no lights; it is the wiring link between compatible Baja Designs kits and the factory upfitter circuit. A vehicle-specific harness avoids splicing into factory wiring to reach the auxiliary circuits. This harness is Baja Designs part 600101 for the 2024-2026 Toyota Tacoma.
Anything a kit needs beyond the box, or any harness option sold separately, is listed in that kit's fit notes.
Features
Uses the factory auxiliary switches
The harness ties compatible Baja Designs kits into the vehicle's own upfitter circuit, so the lights answer to the switches already in the dash.
Made for this vehicle
Connectors and lengths are set for this vehicle's wiring layout rather than being a universal loom.
Works with listed kits only
Compatibility is limited to the Baja Designs kits named in the fit notes, and some kit versions are excluded there.
No lights included
This is a wiring part. Lights and brackets come with the Baja Designs kits it connects.
Cleaner cabin, fewer switches
Controlling lights from factory switches removes the need for separate toggle switches mounted in the cabin.

Installation
The lights mount at the rear of the vehicle on brackets made for it, and the harness routes forward to the switch or trigger the kit uses. Aim the lights at the ground behind the vehicle so they light the work area without dazzling anyone following. The fit notes below cover bumper compatibility, wiring options and any modification.

Warranty, Shipping & Returns
Warranty. Baja Designs warranties cover defects in design and manufacturing only, and the term depends on the product type. LED light bars and auxiliary lights for recreational use carry a limited lifetime warranty capped at 49,930 hours of operation. Brackets, wiring harnesses and switches that Baja Designs resells from other makers carry that maker's own warranty, which Baja Designs passes through. Installation errors, wear and tear, misuse, accidents, collisions, modifications and installation labor are not covered, and claims need proof of purchase or product registration. Shipping. The carrier and ship method are set by the size and weight of the carton when the order is placed. Inspect on delivery. Open the carton when it arrives and check every light, bracket, harness and hardware bag against the kit contents before you start the install. Report shipping damage or a missing part right away, before anything is mounted.
Returns. Unused items in their original packaging can be returned within 30 days of delivery. If an item arrives damaged, defective or wrong, return shipping is on us. See our Returns & Refunds Policy, or email support@prestigetruck.com with any question.
About Baja Designs
Baja Designs began in San Diego, California in 1992, started by riders with a habit of racing the Baja 1000. Its first product turned pure dirt motorcycles into minimally street-ready dual-sport bikes, and its work tuning race lights for night stages earned its engineers the name The Scientists of Lighting.
From motorcycle HID race lights the company moved into truck and buggy racing, and in 2005 it ran its first forward-projecting LED light bar in the Baja 1000. That race program still feeds the design of every LED pod and bar the company builds.
Today Baja Designs lights trucks, Jeeps, SUVs, vans, UTVs and motorcycles, using its Lighting Zones method: pick the right lens pattern for each job and put it in the right place on the vehicle.
