Good news and bad news....
Good newd, Thanks yo Jeff for pointing out the 6 pin harness. I traced it into the inside of the trunk. Plug and play just fine.
Bad news.
Allthough the duadbeam Japan lights fit and plug to existing harness. They do not function. I need to find which wires I would need to move around to power the ballast for the lights to power on. As well as the led turn signals.
it is definitely not in the right sequence. Nothing works except the led turn signals turn on and stay solid when I turn my high beams on.... the struggle.. if anyone with good knowledge of the wiring diagrams would like to help please do so. Thank you in advance.
i think you need some kind of other harness since you have a 2014-2016 model, ik the 2017+ models can just can do plug and play
Both 2014-2016 and 2017 harnesses are the same. They plug and play to either headlights.
What is different is the wiring configuration. For that I need to find out what changed.
if possible maybe all I would have to do is move some of the pins around.
Or else I would have to find out if re-woring back to the ECU is necessary. Really hope not...
if if one of you know how to read the wiring diagrams between the two and see what changed. Please let me know.

Like I said, Body ECU may have to be swapped for the new one and wires from original Body ecu have to re-pinned at the body ECU itself and reuse that wire.
This is so that Highbeams can work. Highbeams work via CANBUS signal
Low beam can work just by re-pinning at the headlight plug
I'll try to highlight the wires that are different when i come up with some time next week.
Does you car have AFS, do the new headlights have AFS?
Jeff
I don’t believe neither my car or the headlights come with AFS.
I am not 100% however. And all my research indicates it doesn’t.
this pictures show my previous headlights and new headlights with a motor attached. Which I am guessing it is for auto leveling. Unless I am completely mistaking and both my car and new headlights do have AFS. In which case the wires would be present.
I am also attaching a picture of the 6pin harness which powers the turn signals and the motor.
Like I said, Body ECU will have to be swapped for the new one and one wire from original Body ecu have to re-pinned at the body ECU itself and reuse that wire.

Thank you SpecOne, you have been of amazing help. I still carry hope that I won’t need to swap the Body ECU, that’s going to cost me some money if I have to do so. Can we try and make the lights work without changing the ECU? Even if it’s juts the low beams for now. Maybe I could even find a way to power high beams at the same time of the low beams with share power?
I have been helping Edwin in the background trying to decipher the wiring of the two.
The initial links of the wiring schematics of the two setups he shared are on my Google drive.
I am pretty close to understanding how this works best I could without being there.
Here is my findings
2014-2016
-Powered by 15 AMP fuse
-Has a SOL wires from both headlamps going to a module called "Semiconductor Power Integration ECU" not show in 2017+
-Has RLEW and LLEW wires coming from ECU to the headlights, not present in 2017+
2017+
-Powered by 30 AMP fuse at the fuse box instead. VERY IMPORTANT difference, extra power to power the ECU/ballast on board the headlights probably
-Has CANBUS wires instead that seem to have taken place of RLEW/LLEW wires
-Rear Height sensor for Auto Level headlights go directly to the ECU on the headlights (whereas the 2014-2016 not sure where it goes currently, need to do more digging)
-One "main" headlight ECU on driver side and then one wire goes from one headlight to the other to "talk" to eachother
-Looks like Added Ignition Power for the ECU?
Here is the connectors for the 14-16 and the 17+ setup pointing out which wire should do what
