Wire back up cam help

I need to wire my wireless backup cam. The camera itself is not an problem but the screen is something I'm left wondering about: I need to get a fuse tap on and "ignition on only" circuit for the hot wire. Which would you recommend? Is there a good place to tap into a ground under the dash?

Thanks.

You can run a ground wire to base of the A pillar. The pink wire from the ignition switch is "run, bulb test, start". Any pink and black wire under the dash will supply the same power.

Going to add my wireless backup cam this weekend. Light green going into the tail lights for the "on in reverse" hot wire- is that correct?

Green is correct.
