BMW Auxiliary Power Y-Splitter Harness — 12V Single Ampseal Output and 12v BMW Output Type 2

BMW Auxiliary Power Y-Splitter Harness — 12V Single Ampseal Output and 12v BMW Output Type 2 Plugs directly into the auxiliary power connector on your BMW's wiring loom and splits to two individual Ampseal connectors, providing a clean switched 12V power and earth supply to two accessories simultaneously. How it works BMW motorcycles are fitted with a switched auxiliary power socket on the loom — typically located at the front left frame or under the tank fairing depending on model. This harness plugs into that existing connector and splits the output into two independent Ampseal outlets. Each outlet provides 12V positive and earth only — there is no signal connection. Mating Ampseal connector included so you can crimp directly to the wiring of the accessory you want to power. Plugs into the BMW auxiliary loom connector — no cutting, no splicing Splits to one Ampseal output and one BMW output — run two accessories from one socket Switched ignition feed — powers off with the ignition, no battery drain 22 AWG weatherproof wiring — built for long-term motorcycle use Mating Ampseal connector included - crimp directly to your accessories Power and earth supply only - no signal wires, no CAN bus interference What can I power with it? Any 12V accessory that uses an Ampseal connector or can be wired to one, and any accessory that uses the BMW loom connection - for example: USB chargers and power banks GPS / sat nav units Heated grips or heated clothing controllers Dashcams and action cameras Intercoms and communication systems Important: this harness supplies power and earth only. There is no signal connection. It will not interfere with CAN bus, ABS, traction control or any other electronic system on the bike. Installation notes Difficulty: Easy. Estimated time: 10–15 minutes. Locate the auxiliary connector on your loom (front left frame or under tank fairing — varies by model and year) Plug the harness in — no tools required for the main connection Crimp the included mating Ampseal connector to your accessory wiring Verify polarity with a multimeter before connecting — BMW wire colours vary between models and years Note: connector location and wire colours vary by model and year. Always verify your plug location and polarity before connecting accessories. A 22 AWG feed is suitable for low-current accessories — for high-current loads such as heated clothing systems consider a direct battery feed with inline fuse instead.
