2017 rear wiring questions

i have 2017 tacoma that I bought. The bed had been removed and set back on the truck. I have a few question about connecting the wiring. First question is the LED lights inside the bed at rear near the tail gate. These wires where just bundle up and stuck in the tail light area. Where do they run to and plug in? Next the rear bumper tag light harness, it looks like I have two possible location it could plug into. Is it under the truck just right of the tag area or just left of the tag area? Last is the rear back up camera wire hanging down from tail gate, which of the two is it the right or left plug in?

 

I don't know if the accessories are in here, but this is most of a 2017 SM with wire diagrams from my Google Drive:
