LC250 headlight wiring diagram (1 Viewer)

HEllo everyone,

I am looking for informations related to the wiring of the headlight for LC250.

Because i like the headlight design , I plan to install them on a different car. ( so i have to create all the wirings)

The connector looks like this. According to my research, the toyota reference of this connector is 90980-12A92.

That connector connect to the Headlight ECU with is located under the headlight . i found below informations :

My questions are:
1- Does anyone knows the meaning of the label on the diagram : LINL, IGR, ECUB, TNS, SGR, SBR, SHRL... ?
: i have to find which one are Low/High beam, DRL, turn signal....
2- Which kind of input signal should i connect ( because my first idea was to connect a 12v + power supply to trigger the light i want to turn on) , i prefer to make sure and to ask before burning the headlight ECU unit: it is so easy to make a mistake.

I want to install the headlight on a different car i am restoring, I have the connectors and the pigtail diagram.. now i am looking for those informations to make it work.
thank you for your time.

I was watching a video on YouTube some time ago, where they were showing the replacement of the round headlights with the square type.
That involved the replacement of an ECU, so I assume that whatever goes in and out of the headlight assy is fed to an ECU via non-discrete signals.
If my assumptions are correct, it would be really challenging to transplant that assy into another vehicle, unless you do the same with the relevant ECU
