Both the GL800 and the F6B are built on the same assembly line so I would think they would have the same wiring harness. The only difference would be what is connected and what isn't. The F6B has no cruise control and no reverse, however, I still think the wiring harness has connections for these.I was told there is a wiring difference for them even though they seem to have the same front end. Does anyone know where to get this info.
