MG2 Sine Ground on GS450h Inverter

I'm a newbie trying to connect my first GS450h setup.
I've had to make up my own wiring loom and would like to confirm MG2 Sine positive and ground

On this diagram they are both the same.

Can someone confirm if:
- top row is MG2 Sine Grnd
- bottom row is MG2 Sine +

Thanks

Yes, been using that diagram, but having removed the original connector pins I've lost those references.
But now I think about it, I can work it out from the original wiring colours on here

I'll figure it out and report back.

SOLVED!
For anyone else stuck with this, the pin on the top row is MG2 SINE GRND

If Xp677 has the original source file maybe they can update the Wiki.

Thanks!
