2007 toyota 4runner wiring of PUMPKIN Android 6.0

[averagedawg]

I was feeling confident.after watching a youtube install of a new stereo install.
All wen't great! EXCEPT for the wiring.

I purchased the pumpkin android stereo.

I couldn't connect to the red circled wiring harness that connects to our factory stereo

So, when i opened up the dash, there was a 3rd harness (circled in red) that I couldn't connect to.
Do you know how to solve for this? Where could I get this harness, or how would I connect to this harness?
I am having problems wiring this stereo to my vehicle.

Secondly, would I have to splice from the power harness to the harness that comes from Pumpkin (assuming I just match colors?). See picture with green arrow?

I attached pictures. Red is the part that I can't connect to. I don't know where / how to connect to that harness today.

Any help would be appreciated... kind of stuck.
