Hi
My first repair was one of these and I had this exact issue because it’s really annoying to blindly get connectors connected from behind
I find I you get the cable and remove the little bit of silver/grey tape fabrics stuff and extend the cable until it’s straight
Before you do that you need to get the logic/motherboard out and you can kind of flip it and connect it fairly easily
It’s a bit bad to explain but if you need any help just ask me in the comments and I can help you at every step of the way:-)
Hopefully this helps
Thanks:-)
