Awesome thank you.

Does anyone have the pinout for the Sumitomo 6189-1092 on the motor?

Thanks for the suggestions. It looks like the connectors might be the following:
Sumitomo 6189-0175
Sumitomo 6189-1092

Not found the last one yet.

I have a GS450H motor but some of the harnesses are missing. Does anyone know what connectors these are, and if they are available?

I dumped some data from my gs450h inverter, some of the values look a bit different to yours, but it could be an error in my code.
Do you know what kind of checksum is being used?

I found the project log of the BMW with the GS450H posted earlier.

I think there is some useful information there.

Thanks for the advice. I got it open successfully.
I took some photos of the inverter control board if anyone is interested. https://imgur.com/a/z4XYsMP
I am also an electronic engineer, so if I can help with developing a board for the GS450H let me know.

How did you manage to remove the capacitor section from the gs450h inverter? It seems very well attached with the silicone, and I don't want to crack it.
