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. The harness runs the light bar and its dust and strobe modes, and it is suited to race use. It is universal fit, so it is not tied to a model or model year.
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

Installation notes
