I need some help figuring out the purpose of a specific cable from my Arctic Liquid Freezer III 420mm A-RGB cooler. Their "manual" doesn't really clarify it at all. I've attached a picture for reference. The manual and video show me how to deal with the other cable (the one marked in red), but I can't find anything about the one in my hand. It connects to the pump and seems important, but it's not labeled and isn't mentioned in the instructions. Could anyone tell me what this cable is for? I'm running a 9800X3D on an ASUS ROG Strix X870E-E motherboard, and while I'm generally good with tech, this is my first time using an AIO cooler, so I'm a bit unsure about it.

Yep, that's a standard 5v aRGB plug. You should find it mentioned in the last slide of the installation tab in the manual you shared.
Exactly! Just look for that 3-pin header on your mobo when you get home.
That cable looks like an aRGB cable. If you check the bottom of the manual in the "Installation" section, it should mention this. It connects to your motherboard for RGB control.
Ding ding ding we have a winner!
Ah, so I did miss it entirely... Just to be clear, I'm looking for a matching pin on my motherboard, right? That green circle in the picture I linked should match?

Apparently I am blind, yep. So just to confirm, it doesn’t connect to the other cables they gave me, but goes straight into a 3-prong matching header on the motherboard?
