Overview

The Baja Designs S8/IR wire harness, part number BAJ640122, is a complete wiring harness for Baja Designs S8 LED light bars. It is offered with a Mode-2 bar and rated for a maximum of 325 watts.

Key features

  • Complete harness made for Baja Designs S8 LED light bars
  • Supports the dust and strobe modes of the light bar
  • Maximum rating of 325 watts
  • The harness is built to make installation simpler, with the wiring prepared for the light bar.
  • Designed for race use

Matching the harness to your bar

Matching the harness to the light bar matters more than matching it to the vehicle. Confirm the bar is an S8 model, then check that the connector style and wiring colors line up before you cut or extend anything. A mismatched plug is a common cause of a harness that will not work on the first try.

Race use means the harness will see vibration, dust and water. Route cable through grommets, use drip loops at connectors, and keep splices sealed. Mount the switch where it can be reached without leaning across the cab, and keep the wiring away from suspension arms and driveline parts that flex through travel.

  • Check connector style before cutting wire
  • Use drip loops at every connector
  • Keep splices sealed against moisture

Questions & Answers

What is the Baja Designs BAJ640122 harness?

It is the Baja Designs S8/IR wire harness with Mode-2 bar, a complete harness for S8 LED light bars. The part number is BAJ640122 and the title gives a maximum rating of 325 watts.

Will this harness fit my Jeep or other vehicle?

Universal fit is given and no vehicle, year or chassis code is named, so the harness is not tied to a model. It wires Baja Designs S8 light bars, so match the light bars rather than the vehicle.

Are the S8 light bars included?

No. The S8 LED light bars are not part of the package, and the harness needs them to work. Pair it with compatible S8 bars before installing.

What is the maximum wattage?

The title gives a maximum of 325 watts for this harness. Keep the total load of the lights you connect within that rating.

How do dust and strobe modes affect wiring?

Mode changes travel through the light bar's control wiring, so the harness has to carry that signal cleanly. Test each mode on the bench before mounting the bar, and recheck connections if a mode skips or stays stuck.

What should I check before a race event?

Inspect the harness for chafed insulation and loose connectors, and confirm the fuse seats firmly. Test every light mode once after the wiring is complete, then keep a spare fuse in the vehicle.
