I need some wiring help & expertise.
This is what I did.

I picked up a set of Denali D7 Auxiliary Lights from Steve @ A Bike Thing
I also picked up a Thunderbox - Model TB-U02 - Thunder Box (TB) - HealTech Electronics Ltd.
I wired up the Thunderbox with the wires +ve and -ve going to the Battery.​
I wired the auxiliary lights, the wires +ve and -ve going directly to the Battery and the White wire going to the +ve in the Thunderbox ( as a split live wire ).​
I turn ON the ignition , the auxiliary lights do not come ON ( as expected ), I then START the bike, a few seconds later after the engine is running, the auxiliary lights come on at 50% as DRL ( as expected ) They are bright as daylight @ 50 % - check the video at 31:00 to the end, to see full intensity @ 100%
I turn OFF the bike with the Kill Switch and turn OFF the ignition. The Auxiliary lights are supposed to turn OFF after a few seconds, but they do not ( this is an issue )​
Also I need help locating the high beam wire, so I can connect the Denali harness wire to the high beam wire of the bike, so I can control the high beam of the auxiliary light on the same OEM Switch of the bike.​

Any help with a picture explanation will do ;)

Higly suggest to NOT play with oem wiring of the front light. As the LED unit on the honda bikes are a bit different to other brands. Few owner of africa twin also have the same issue witht the thunderbolt . Fit it using the ignition controlled mode , seems the only way to getit work properly.

Get the Plus+ for the Thunderbox from the red cable ( rear under seats)

Thanks @Ghostrider.1127 (y)
I sup I will have to go pick up > DENALI DRL WIRING HARNESS WITH 3-POSITION SWITCH <
I am still hoping there was a better way to do it, without having to add another switch on the handlebar.

Did you get it sorted yet?
Hello @Otown , No I could not get the Thunderbox cutting power OFF to the lights when I turn off the bike + I could not find a clean way to connect to the high beam blue wire or to the OEM switch ( also @Ghostrider.1127 recommended not to try messing with the high beam wires & he also mentioned to take the trigger split live from the USB's red wire instead of a trigger from the Thunderbox as the African Twins also having the same issues)
I have now ordered the Denali 3 way switch harness ( should be here in the next 2 to 3 days ) and will hook it up this weekend the ugly way ( having an additional switch on the handlebar to low high off )

Issue resolved (y) bypassing the Thunderbox (TB-U02) & also not trying to connect to the high beam blue wire on the OEM Switch.

I picked up the Denali 3 way switch (Low, Off, High ) harness.
Routed the trigger wire directly to the Tail light switched live wire.
These 3 tail light wires come to a connector, which is just under the rod that hooks up your seat cowl / rear seat. Just before the connector, I posi tapped it to the brown wire which is a switched live 12 V ( 2021 1Ltr Black Edition - has Yellow / Green / Brown wires going into this connector )
DO NOT take a switch live from the USB wire ( this USB option comes standard on 2021 models ) under the seat cowl as it is not a 12 V feed.
I bypassed the Thunderbox (TB-U02) outputs 2 x 16A as the Denali D7 light pod pair draws 10A. I did not want overload the Thunderbox, so I can use it to power up my Phone USB, GPS etc. Also in talking to Denali, they recommended to bypass the Thunderbox & that way, I would get pure definite draw of 12V, if I went directly to the switched live wire of the tail light.
I hope this helps others how to get a switched live trigger connection.
