Help electric Fan wiring - Where to tap into switched 12V+

[rosphill]

I've been struggling to get my SPAL electric fan wired into the stock AC fan wiring for a long time and finally decided to give up on that.
Bought a standalone fan wiring kit from Summit Racing.

I want to tie it into switched power 12+ only on when ignition is on.
Is there a connection in the fusebox like that?
Would really appreciate any help because it is basically the only part of my swap left unfinished.
Thx

You can tap it into the aux box next to the fuse box. One is constant the other is switched.

Is this the one? Looks like a light green and a red wire? Hard to tell I'm cursed with the red/green colorblind. That looks like a easily accessible area to tap into so thats cool.
