If you measure resistance across all possible ground pins, is there any resistance? If so, then there is one big ground plane.

I'd have to check next time I'm around the car, probably wont be for two weeks, but if it's anything like the DIYPNP mainboard, then they are separated...

They are not separate on the DIYPNP. The ECU (processor, etc) uses the same ground as the pulsed high-current and medium-current devices.
