Location for front camera and firewall cabling

Just picked up a 2018 new to me TRD Sport with only 16K miles on it. Coming from a 2010 Tundra with 107k.

First thing I discovered was - no freakin CarPlay - nice job Toyota... so - I read about 100+ pages here on this awesome forum and have a pile of stuff from Crutchfield arriving tomorrow for the WT7600 install (not as great as the 6600 but out of stock everywhere except some dude on Amazon, so it may or may not be legit). That's OK - enough posts on how to flush mount and trim and all that good stuff...

ANYHOW - I have this extra Natika camera laying around I was gonna install on my racecar and never did... So I was looking at the non-stock, can someone here identify it, front grille on the new to me Taco - and wanted to ask the following:
1 - where do people install this - the most obvious spot in center has the adaptive cruise radar module
2 - where do folks run the wire from the front through the firewall?

I was thinking off center in either of these 2 openings where the red boxes are, as there enough height for the camera and enough material to drill and mount...
