Does the base have a pigtail to its connector? If so, under its black outer insulation should be the same colors of wires. Where are the thick red and black wires for power?

If you remove the controller, per this facebook post, you can expose the controller and the entire wiring harness. From there, you can confirm that the red/black wires go to the controller abnd are nattery plus/minus.

The identity of the other four wires will have to be inferred fro, where they go on the harness. Probably two of them are for the charger. MAybe two others are for themocouple. I cannot see a bike this cheap using proprietry data to/from the battery,
