The cables are too short to reach if they are threaded through in any other orientation. Slowly pull the upper display assembly away from the upper case. Make sure that the various ribbon cables are being fed through the slit in the upper case.

Getting the new assembly ribbon cable through the hinge is excruciatingly tedious. I tore my cable when I tried fishing it through with a small hooked pry tool. Learn from my mistakes

Whatever you do, don’t accidentally hook the display ribbon cable into the slot for the speaker ribbon cable when reassembling. It holds it too firmly, and will rip easily. I now have to spend $15 on a new lcd ribbon cable.
