OK is this correct?
Those 2 holes confuse me a little bit in the middle
one is to a brake and the other is for forward and reverse. Why I am confused about it is that there is just one pin for each, wouldn't there be a + and - for each.
If I'd looked closer at the photo in the first place I would have realised the multiplug was different to the old controller. Even though it has 23 pins instead of the old 14 pin version, the -ve ground wires from the throttle, brake switch, reverse switch and hall sensors do not appear to connect through any of the multiplug pins, so they would need to be connected directly to the B- connection instead.
Hopefully this updated explanation of the HPC300A/500A controller connections will help:

I think these details are correct now.
