This Baja Designs 640093 is a single upfitter harness that ties Squadron, S2, and S1 LED lights into a vehicle's factory up-fitter switch circuit, so the lights can run from a switch already in the cab. The manufacturer built it for factory up-fitter and uplifter switches and lists Dodge, Ford, and Jeep applications. Owners on user forums describe it as a cleaner route than cutting the switch and components off an LP-series dual harness, a method that confused some buyers unfamiliar with relays. The manufacturer also says the harness can feed switch panels such as Switch Pros or sPOD units, which gives you room to expand later.
The real value is avoiding a messy splice-and-relay job. The harness uses a two-pin connection with splice terminals, so you are matching a connector rather than improvising wire taps. If you plan to run two lights from one harness, the manufacturer requires a separate 2-pin splitter. Mounting hardware is not included, so budget for brackets separately. Searches for "Squadron S2 upfitter harness," "plug and play upfitter LED wiring," and "Ford upfitter switch light harness" will bring up this exact part number.
The product title references the Ford Raptor, but the manufacturer lists this harness as universal, so confirm your model year's upfitter wiring before ordering. For first-generation Raptors, the manufacturer's fog pocket instructions describe two separate connection points, one behind the glovebox and one in the engine bay. The manufacturer's A-pillar kit instructions for 2017–2018 Raptors also call for a clean chassis ground for the negative lead and recommend photographing the harness routing before depinning anything.
No. The manufacturer states the switch is not included. The harness connects to the factory upfitter switch circuit already in the vehicle, and the manufacturer says it can also integrate Switch Pros or sPOD panels.
The manufacturer specifies a 2-pin splitter when two Squadron, S2, or S1 lights share a single harness. It is not included with this part.
The manufacturer lists this harness as universal and describes factory up-fitter switches across Dodge, Ford, and Jeep vehicles. Confirm your model year's upfitter wiring with the manufacturer before ordering.
Owners on user forums rate this as a fairly simple install compared with relay-based setups, and the manufacturer's instructions for Raptor upfitter wiring describe a straightforward sequence: locate the factory upfitter wires, clamp the splice terminals with pliers, and route the harness with zip ties. Plan to find a solid chassis ground, since one owner on a user forum reported the ground eyelet was too small for the factory stud and had to be reamed out. Photograph the harness routing before you disconnect anything, and secure the harness at the grommet pass-through so it stays clear of moving parts.
