Street Cup Switched Ignition

Hi Folks.
I have a 2019 Street Cup and want to fit a Denali 2 power hub. My problem is which wire do I need to connect the unit to for a switched live. I know the red and black wires go straight to battery and earth - the yellow wire is for the ignition live.
Hopefully someone can point me in the right direction.
Going to be fitting a dash cam on bike - also have a few other goodies to put on.
Have changed both rear suspension for Fox and silencers for V&H ones.
Will put some pics up when all sorted.
Thanks for reading

 

I have the charger port under the seat, but am fitting a Thinkware dual cam system to the bike. I'm wanting to use the power hub in case I install anything else on bike and am able to keep the wiring to a minimum. Also not sure if the usb hub is capable of powering the Thinkware module box.
