The Y splitter was necessary to clean up some wires under the seat form multiple Ciro products.

Excellent product - Rear End Lighting Wiring "Y " Splitter

Such a small item makes adding additional Ciro products so much easier, quicker and more convienent dealing with the wiring nest under the seat.
Amazing product.

Bag Blades - install with Splitter

I have the Latitude & Machete lights already installed on my RK Special. I wanted a little more visibility for my back end so I installed the Bag Blades. Since I already had the other lights I was wondering about the hook up and if I needed additional plugs. Darren @ customer service said to order the splitter with the Bag Blades. I didn't have to change any of the wiring I had already done with my previously installed lights. Plugged in the splitter to the existing harness then plugged in the Machete and Bag Blades to the splitter.....Done! Everything operates perfectly. Thanks Darren!!
