Default H4 Harness upgrade how to connect LED headlights

Hello, i'm from Amsterdam and new on the forum. I have done an H4 harness upgrade on my cherokee XJ 2000 limited and want to connect my new Loyo LED headlights. However, I discovered that I not only have an H4 plug on my old headlights but also 2 other cables: one blue and one black (see attached picture). Does anyone have any idea what these cables are for and whether they are relevant to my new LED lights? could find any similar situation on the internet yet.
Hopefully someone can point me in the right direction,

Thanks for the answer, can it be my headlight leveling system?
Apparently this is mentioned as an 'europe' thing in the parts manual.
maybe that's why i can't find any examples on youtube etc.

I don't think so.
I don't have a picture but have seen pictures of them.
They have a actuator and rods kinda like the door locks to move them so....

Hello, ok thanks. Another question if i may.
(if recently bought this cherokee and try to learn new things along the way)
To connect these DRLs wires to my new led headights i prefer to have a plug-in plug-out solution.
I'm afraid this new led lights will not pass the annual inspection. (strict rules in the Netherlands)
So actually i want to be able to simply change the led lights for the original headlights once a year.
The main H4 plug is already a plug-in plug-out option. However, the DRL's i still need to wire together.
So long story short: How to best connect the DRL's wires to my new headlight using a plug-in plug-out connection? any advice?
