Unfortunately, I don't know where you can obtain these connectors, perhaps GM in China may be able to help
(sales@goldenmotor.com).
As far as the pinout details are concerned, the Vector controller wiring diagram shows the important wiring connections on the 30 pin connector:

I also found a pinout diagram for a LingBo Controller which appears to be very similar to the VEC200 controller:

Hopefully you can find the information you are looking for from the above diagrams.
