FC to ESC Wiring Discrepancy

I’m upgrading my quad to an 8S config, and want to use the FETtec 65A 3-8S 4-in-1 ESC with the Kakute H7 V2 FC. I’m trying to figure out the wiring for the connector.

All the pinouts are straightforward except for 2 of them. The FC has a GND and CUR pin while the ESC has 2x GND pins. Does it matter which goes where here?

just skip the cur wire, your esc has telemetry so you dont need it.

Yes, it matters. Connect the GND to both GNDs and leave the curr pin open.

Is there a reason why both GNDs on the esc need to be connected (as opposed to just one)

The reason is: If they are separated they need to be connected together. But I can not guess if they are separated.
