The Baja Designs 613609 is a 55-inch universal wiring harness splitter that lets one lead power two lights. The manufacturer describes it as a plug and play 55 inch universal wiring harness compatible with the OnX, OnX6, XL (Pro and Sport) and XL-R (Pro and Sport) LED lights. Its terminal connector is listed as two three-pin connections, with splice connectors as the terminal type. A factory-built splitter avoids a homemade junction on the same run, and owners on user forums have used the 55-inch length to merge two lights into one cable. Its universal fit means you choose it by light model, not by vehicle year and make.

Installation is mostly routing and connecting. Per owner accounts on user forums, the male ends plug into the two lights, and the splitter's single cable then runs to an extension or upfitter harness. One owner noted that the wires on the switch-side harness were short, so plan for slack when you route the cable. The manufacturer's install sheets for companion harnesses call for disconnecting the battery ground before any work and keeping wires away from hot, sharp, or moving parts. The listing shows no mounting hardware and no switch included, so budget for a separate switch and power harness.
The manufacturer lists it for the OnX, OnX6, XL Pro and Sport, and XL-R Pro and Sport LED lights. It is a universal part, so match it to the light model rather than to a vehicle.
The manufacturer's specifications list no switch and no mounting hardware. Owners on user forums have paired it with a 10-foot extension and an upfitter harness to power the lights from factory aux switches.
The manufacturer describes it as plug and play, but its terminals are splice-type. Connecting it to your power harness may require crimping or splicing, so confirm the terminal details with the manufacturer before you buy.
The light-side connection is straightforward, since the splitter's three-pin ends mate with the lights. The harder part is the power side, which is where owners on user forums report the most difficulty. Disconnect the battery ground before you start, then route the cable away from heat and moving parts. Companion harness instructions from the manufacturer list a 10mm or ½-inch socket for battery terminals, plus ½-inch and ¾-inch drill bits if you mount a switch. Plan for extra slack in the wiring and test each light before final mounting.
