No, you are mistaken . Step 23 was for the LEFT speaker. Anthony is correct stating that right speaker disconnect is missing from this guide. NOW is the time to disconnect the right speaker from the LB!

Before I disconnect the cables, I use different color sharpies and draw a different color on each one’s head & then I take a picture of the cables connected to the board. Pic is my reference of which cable goes to what connector.

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.

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.
