The Baja Designs Squadron 2.0 4-Pin Deutsch 2-Light Harness (64-0055) is a universal two-lead wiring kit that lets one 3-position dash switch run a pair of Squadron 2.0 Sport or Squadron 2.0 Pro auxiliary lights. The manufacturer's install sheet covers the full build: battery feed, switch, backlight trigger, and light connections. Building the same circuit from bulk wire and generic connectors takes more planning, and a factory-terminated Deutsch-style plug at each light makes it easier to service or swap lights later. This is the harness to pair with Squadron 2.0 lights on a bumper, roof, or A-pillar setup, where a clean, repeatable Deutsch connection matters more than a few dollars saved.
Fitment is universal, and the harness is built around the Squadron 2.0 lights rather than a specific truck. The manufacturer's install sheet says each lead can carry up to 14A of lights, and splitters or extensions can add more lights per lead. The DIY work centers on a few steps: a ring-terminal battery connection, a 3/4" switch hole drilled in the dash, and routing the switch lead through a firewall boot. Owners on user forums note that if your auxiliary circuit cannot handle the combined draw, you can wire the switch leads to the vehicle's aux output instead of using the rocker switch. Search terms this harness matches include Squadron 2.0 4-pin Deutsch harness, 64-0055 wiring harness, Squadron 2.0 backlight harness, and dual light off-road switch harness.
The harness is listed for Squadron 2.0 Sport and Pro lights. The manufacturer's Squadron 2.0 Pro materials specify a standard 4-pin Deutsch connector, which matches this harness's connector type.
The manufacturer's install sheet says each lead can carry up to 14A of lights and that splitters or extensions can be used to add lights on each lead. Check the total current draw of your lights against that limit before adding more.
Yes. The manufacturer's install sheet includes a backlight trigger lead along with the switch and power leads, and the manufacturer's Squadron 2.0 Pro page lists selectable backlight colors on that light.
Per the manufacturer's install sheet, you will need a wrench, a drill with bits up to 3/4", and pliers. Start by disconnecting the negative battery cable, then connect the red ring terminal to the positive battery cable and the black ring terminal to chassis ground or the negative cable. Route the light leads to their mounting points and plug them into the lights. Drill a 3/4" hole in the dash, press in the switch, and route the switch lead through a firewall boot to reconnect it. The sheet suggests taking a reference photo before de-pinning and re-pinning the red connector, and it lists BD PN 64-1120 as an extension if the switch lead is too short. Before wiring to a vehicle's auxiliary circuit, confirm that its amperage rating covers both lights.
