This LandPride kit is often refered to as a "true" 3rd function because it can be operated using only an electroic button on the loader stick. 

There is also a cheaper Kubota branted kit BX2412 that is a diverter. In this case the loader stick button diverts the loader curl function to operating the 3rd function remote. 
This does give some flow control, but can not operate at the same time as the loader's curl function. This version of the kit works best for thsoe who remove their loader often, as only an electronic wire needs disconnected. The LandPride version requires hydraulic hoses to be unhooked.
