Best wiring route for dual aux/bento box fan

Im about to wire it up but im wondering if anybody else has done it? And where they ended up connecting or splicing it to? I cant find a fan diverter for the main aux fan, which is really what i want for running the bento box on the right side. If I could find a diverter, I would just splice into the other aux fan.

I want to be able to run both fans when printing pla but also run the bento box when printing asa or abs.

I either need a fan diverter or a way to wire and control the 2nd aux fan.

EDIT: I ended up doing the following.
If all else fails, maybe ill just run a rocker switch to the left fan and just shut it off when i only want to use the bento box.







Can I ask why 2 fans?

@NicePrintTiger
The overhangs. I can also run the fans at half speed for silence now. The bento box is to cover for the loose carbon filter.

Theres a voron on youtube that uses dual aux fans for 3 minute benchy
