John, Did you find a solution? I have the same situation but need to add the actuator component as well. The Rhino Sport Bar 2.0 did come with a toggle relay but want to tie into the existing Auxiliary Control Switch. I would like to find a headlamp switch to keep the original look, just add flood lights.
