Which flex cable did I cut?!

I cut the flex cable that is exposed in the bottom left corner when I was replacing the back glass. And where can I find a parts diagram for this phone model?

Answer this question I have this problem too

Is this a good question?

Seems pretty obvious that you've cut the lightning port flex cable. If you look at the part being sold here on iFixit, the second (back side) picture shows exactly the area you're indicating.

Looks like iFixit hasn't quite gotten around to making a guide for that repair, but luckily there's a Spanish site called Nadie Me Llama Gallina that has just what you need to do that repair.

Of course, since iFixit depends heavily on users helping to make guides, you can always add to the knowledge by taking lots of pictures during your repair and using them to create your own lightning port flex cable assembly replacement guide! It's fun, easy and will be greatly appreciated by everyone who comes after you.

I purchased this phone as is. Someone had previously tried replacing the back glass and front screen and quit. The one was functioning when I purchased it. Now I just need to figure out which flex cable it is. Thanks so much for any help.
