Mini golf cart controller problem - Help!

I've got a controller out of a fairly new 4 wheel Chinese mobility cart (has a steering wheel and looks like a tiny one seat golf cart). The part # on the controller is CID 932 B9D. It is a 10 connector controller (one connector is not used) with built in reverse - 36 volt 40 amp with the 31.5 voltage protection. The controller looks identical to a CT-660B9, but with 10 connectors. Any Idea where I could locate one if these? Is there another controller that I could use (and not have to do extensive modifications?
Any suggestions would be appreciated.
