LE mirror tap & factory service manual?

I have just bought a 2021 AWD-e LE, adding to my 2012 Gen 3 Prius.

Wondered two things:

• the mirror is manual, no power or lights - all fine.
  Is there anywhere in the vicinity that I can tap a 12V radar detector mount?
• related to the above, is there a factory service manual PDF or similar around?
  I have paid around $20 for these for other cars, but can't see anything for gen 4 prius.

First commute in it tomorrow! It has 45mpg from my Gen 3 to beat... let's see!
