16 and 17 are production date cut off, before Aug 2019 and after Aug 2019. I've a 2020 with a build date in Jan 2020, so not sure which applies to me. Lets say I go with after Aug 2019 - how to the colors apply? Red is power, green v+, blue v- and white is ground? Or does it change when I reach the other side of shield? Because the red becomes green on the othee end as per diagram.
And V+ goes to middle wire in composite and v- goes to the shield of composite?

Because on bottom of diagram (i guess camera side of the harness) says: W-BGND, G-BCV+, L-BCV-, R-BCB+
And other side of harness says: W-BGND, B-BCV+, R-BCV-, G-BCB+.
So green becomes black, blue becomes red and red becomes green. Also there are 2 whites in harness - one is combination with the black wire (CANL and CANH?) other in combination with blue. White and black are pin 1 and 4 - I guess i pick the other white?

Wow.. it totally threw me off. What part of diagram to look to come to that conclusion?

And one final question - I'm posi-tapping the harness, so should I posi-tap the camera side or the other side? Because I see an additional gray wire coming on other side (so there's some magic wiring in the shield).

Awesome. This matches what I was thinking. And is there a reason we should keep the composite wire's shield unconnected and rather ground it directly at the camera (vs relying on the Lsalit unit to ground it internally)?

Update - such a waste of time (and money) I did on this 'upgrade'. Bought a lot of things including tools and all wasted 
. Reason for me trying the upgrade is that I didn't find the noise/ clarity acceptable on the $20 cam I had installed. There came the $600 cam I salvaged from my 2020 RX accident and thought it would be a perfect thing to put. After installing it the fish eye effect was not that good and the placement required it to mount almost 3/4 inch outside the grill. Thought to try the old cam again, I redid the wiring, with a proper ground including grounding the shield of composite cable. Worked out wonderful with no noise and better clarity than the lexus oem fish eye cam.
Learnt a lot out of this, specially the importance of grounding on AV cables.
