Replaced right headlamp, light bar half ON

[Fnlucci]

Hey guys,
I have purchased this salvaged f150 lariat 2023
And Have repaired the car and replaced one headlight ( side where the light bar is off) due to the accident it had I bought this headlight off ebay for 675$ and it is OEM

Now the light I purchased is causing some trouble :
1) Full beams do not work on the headlight I installed
2) Turn signal does not work on the headlight I installed
3) Lightbar is half ON
4) The Headlight I installed is not connected with the light control panel (does not turn off when I set the lights to off) but it turns off after a long period of time

I checked forscan DTC and it is giving me two errors regarding this Right headlight

I am wondering now, is it possible that the headlight I bought is for an F150 pro and requires reprogramming the headlight (to send power to the lightbar) since pro’s do not have a lightbar?

or
Is there a connection I missed and now it is not turning on the light bar?

What do you guys think? Andy help, idea is appreciated
Thanks!

Probably needs a LIN bus initialization of the new headlight using FDRS. Basically it's not being recognized properly on the network. And each half of the lightbar is powered by one of the headlights.

How can I do that?

I have FDRS...I also have FORSCAN but I don't know if it can do bus initialization of new parts on the network. I've never used it for that, just changing asbuilt values.

In FDRS you download and run the tool routine and it looks for and adds unrecognized modules to the network:

There may be a way to do this in FORSCAN...but since I would normally only use FDRS for that function, I haven't investigated whether FORSCAN will do it or not. You'll have to poke around in there and see if there's a similar command.

So I fired up my FORSCAN laptop and it does indeed have a function for initialization of new modules. But I'm guessing you found that by now.

Select the wrench icon and then scroll down until you find the Body Controller and then run this procedure.

There is a thread here on the site - look for adding a lightbar to a Pro. I believe they disclosed how to turn the power on for the lightbar, which as noted is each half powered by the headlight on that side. You have to increase the voltage from the module it connects to.
