LP4, Upfitter Harness Single Light Baja Designs

The Baja Designs LP4 Upfitter Single Light Wiring Harness (640188) is a purpose-built single-light wiring solution designed specifically to integrate with power management systems — sPOD, Switch-Pros, and factory upfitter setups are all on the supported list. This is not a generic wiring kit adapted after the fact. Baja Designs engineered the connectors and circuit logic to match what these power modules expect, so the integration is clean from the start.

For builders who want a tidy, intentional electrical setup rather than improvised wiring, this harness is the right call. It ships as one complete harness, ready to pair with your LP4 and an existing power module.

One thing to confirm before checkout: this harness does not include high/low lock-out capability for the LP series. If your build requires that function — common in trail and work configurations — you'll need to add part 640167 to your order. We recommend sorting out your power module configuration first so you land on the right combination without a return trip.
