I replaced thermal paste on my 2020 Macbook Pro A2251. Everything seems to work fine except half of the keyboard lighting. I suspect I didn't connect the cable properly but unable to find which exactly cable. I can't find a disassembly guide for this particular model anywhere and guides for older models didn't help.
Update: Added a picture

I am not 100% but check the connections by the fans I have marked, 2 of them should be for the BL
@danj to assist further if I got it wrong.

Thanks, but mine looks totally different. I attached a picture to my original post.
@ray68836 Oh I took my image from the device listed guide! Edited the answer.
There must be a mistake. Mine is 100% A2251.
@ray68836 I edited the answer and marked the connections to check.
@livfe Thanks a lot for all your help! The longer cables (top of the image) are most likely from the fans as the fan replacement pictures for this model have them which means I need to check only the other two cables.

Check near both the fans, I think there are 2 connections for the BL

Thank you very much! I'll try to reconnect this cable. Do I have to disconnect the battery just for this?

@ray68836 It is always recommended to disconnect the battery before any internal adjustments are made ;)
