I have received an email from Jetcat and the I/O board i have pictured above is available (Part Number 61108-50).
This has 2 of the new connectors so will allow you to plug the mini GSU into the I/O board whilst it is still connected to the ECU.
Should this not have been supplied with the mini GSU as standard, the one with it is just the same as the one supplied with the P20 and is of no use.
