Legality of Different Battery Connector

[sanddrag]

Last year we were able to use different battery connectors as long as they were rated for more than the ones in the kit and were still quick disconnect. Can we do that this year? Rule <R20> says

The 12v battery must be wired directly to a quick connect / disconnect connector (provided in the kit) that
in turn feeds power to the Main Power Disconnect Switch and Circuit Breaker Assembly.

Does "(provided in the kit)" mean we have to use the one in the kit? If we are allowed to use these, do they have to be available from the electronics suppliers? Following the flow chart, I get hung up on this box

Is the part an Additional Electronics component?

I see it as an electrical, not electronic, component. Can someone verify the usage of these? Our intent of usage is not unsafe or maliciously amateur in any way whatsoever.
