You are correct, John. Per OWC Tech support, no thermal sensor cable needed for the 2.5” HDD, SDD on this 21.5” iMac.

I concur with Anonymous 596. There is a support wall that runs front to back, under keyboard, held down by 2 Phillips screws that will need to be removed & transferred to new upper case. You can see it being touched by index finger in this pic.

Try these Ulta Thin metal spudgers for iPhone repair. Thinner than a credit card, good grasping and slices thru the glue!

I tagged the inverter cables with different color sharpies so as to get them connected back the way they were.

thin ifixit pick opener sliding gently/slowly underneath ribbon cable towards the front edge of mbp did the trick for me. no need for heat.

Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.

Thanks dkraermer2 for that tip of wrapping all 3 wires into a narrow point. I used Capton tape. The metal screw holder needed help as it catches on a ridge in the MB. I used tweezers to “Lift” it over that last ridge.

slight touch of glue secures speaker cable to MB. Use steady light presuure with spudger edge to unglue and then disconnect cable from MB

Take pictures with iPhone of all tricky connectors and refer to them on reassembly:-)
