Question about back of head unit, connections

[MikeRS1981]

I'm installing a Kenwood powered sub to my EX hatch. The doors are a bitch to tap the signal to and route the wires. I'm going in from behind the head unit. There is an extra connection, that isn't being used. Does anyone know what it is used for?

Also does anyone recommend any t tap connectors or something similar in a small profile that I can fit behind the radio in the stock harness?

Thanks for the diagram. Figures the one I questioned isn't in there. It's the middle connector, left side.
