Opinions? Easy way to measure and do it myself?

I have a 2013 Hampton Bay fan. Lost remote, and the fan is currently in the OFF mode. I think I can remove the remote controller, and then I can turn the fan on and off by the pull chain.

I have done a lot of house electrical work myself, but just an amateur. I want to make sure I understand the wiring if I remove the controller. Can somebody assist on how I have to rewire it?

I just took down a 1988 Casablanca Fan. It’s heavy and solid. It even has the old fan control switch still. I’d feel bad trashing it because it still works just fine. Any recommendations on the best place to contact ceiling fan people in my area? I’d put it on facebook for free but I know there is a passionate community around these types of fans and I’d love to give it to someone in this community. I’m located in Western Massachusetts.
