So I had an accident, I had to pay out of pocket. Instead of buying oem headlights I bought the ones on eBay which are $1200 cheaper. The problem is that the wiring harness is not the same. I’m guessing the ones on eBay are for the headlights which are non LED. My car has the ones with the active running light. What options do I have? The lights are mounted but aren’t connected. Do they sell a harness? Help guys thank you

Send it back to the seller if possible. There is no way to retrofit a lessor light than what is in your car already. You should have looked up the number of the light part that you were replacing before ordering since there are 3 levels of headlights. Goodluck.

Ive been looking for wiring diagrams but they’re impossible to find. I need the wiring diagram for the original holagen headlights with 6 pins and the wiring diagram for the LED 9 pin harness

I also ordered this pigtail harness

The pigtail should come with a conversion diagram.
I’ll keep looking, but I’ve never done this conversion so no personal knowledge
sorry
hopefully people will keep looking at these posts

There was a Youtuber video I found by accident where a guy was replacing the headlight on a Mercedes however a previous shop couldn't find out why the headlight was not working. He then explained the wiring and what each one was for, then he said the main issue that the headlight didn't work was because it needed to be programmed.

you happen to have the link to the video?

I think part of the reason for his response was to point out that u may still need programming

@BenzNinja USA maybe can help

I dont think you need programing, but it's a possibility. I havent ruled that out yet because the running lights are on. when i plug them in the running lights stay constantly on. In order to turn it off I need to manually disconnect them.

ALSO upon connecting them the regular/ non high beam lights flash once or twice and then it stops. So maybe that does mean I have to program it?
