The group of wires on the right side of the display is the inverter. Seems like a few steps were omitted, so I'll try to fill in the gaps. Use the T10 to remove the right speaker. It's the big white plastic squarish thing on the bottom right side of the iMac.
It pulls stright up and you can either disconnect it or just leave it hanging. This should release the inverter cable from hanging up the right side of the display (it did for me, even disconnecting the inverter didn't help as the cable was under the speaker, the inverter doesn't need to be disconnected but it might be helpful to disentangle things and it's an easy one to take apart).
The other step missing is to remove the perforated tape at the top of the LCD from the LCD, otherwise you can't really remove it. I found a spudger helpful for this task. I know it's a couple years since the OP posted, but hope this helps someone. Cheers Jeff Kamis.
I purchased this hesitantly for my Mac Mini 2011 A1347 as it was unbranded and cheaper than iFixit options. However, I purchased this with a Samsung 750 EVO 512GB SSD and gave it a crack. I used the iFixit Dual Drive replacement guide which had 37 steps but wasn't nearly as scary as it sounded. I laid out every step on paper so the screws were easy to locate when putting back in. The cable was long enough for the second drive to be on the bottom and I got it all put back in again within about 45 minutes. I booted up and the drive was recognised straight away and needed a quick format and it was ready to go. I wanted a single 1TB (512 SSD and 512 stock SATA) storage drive so I booted in recovery mode and created a 1tb fusion drive by following online instructions.

It worked as expected and reinstalled MacOS, downloaded all of my photos and files from the cloud and I now have a blazing fast Mac Mini with double the storage. Couldn't be happier and would definitely recommend this kit. I purchased this hesitantly for my Mac Mini 2011 A1347 as it was unbranded and cheaper than iFixit options.

Adding a second hard disk to a Mac Mini is a bit like changing the dilithium crystals in the Star Ship Enterprise's on-board sewing machine - it's a bit fiddly! This kit provides the missing bits and the tools you need to complete this job fairly easily (and reducing the overwhelming temptation to employ a lump hammer) and also the option of creating a Fusion drive.
Fusion drive is probably the most effective upgrade you can do to a Mac Mini and has made a huge difference in the performance of mine. For very little cost you get everything you need to complete this operation with the addition of cheap SSD.
