I would look here......Futaba 202-SD-08Gx Series. Whilest this data sheet is not an exact match to your part number with the "BA" suffix it is a reasonable guess that the pin connectoring may be similar to this GK /GYK / GNK / GYSK / GLYK series.

At least you can look at the module you have and see it the power and ground connections are in the same places. If so then it should be reasonable to try connecting the the interface signals up to your kit and trying to communicate to it!
