Introduction
Use this guide to replace the SATA cable on the back of the logic board in an iMac Intel 27" Retina 5K Display (or to install one for the first time, if for example your system only came with a blade SSD and you want to add a second drive).
Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.
Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply.

-
With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed with the iMac laying down, but are faster and easier with an iMac service wedge.
-
If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.
-
-
-
With the cards inserted as shown near the corners, gently twist the cards to increase the gap between display and case.
-
If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the adhesive in the problem area.
-
Begin to lift the top of the display up from the frame.
-
-
-
-
If there is a wire or cable underneath adhesive tape, always pull the tape off first.
-
If the cable is glued to the chassis, use a heated iOpener or a hair dryer to soften the adhesive first. You can then slide an opening pick underneath the cable to loosen it. Never pull directly on the delicate connectors.
-
Slide an opening pick underneath the foam cushion pieces to separate them from the display, and gently pull them off. You may need some double sided tape to re-attach them to the new display.
-
-
-
Use a Phillips screwdriver to remove the nine 3.2 mm screws securing the support bracket.
-
You may need to peel up the display adhesive lining the bottom edge of the iMac enclosure to access the screws.
-
-
-
Pull straight up on the SATA data/power cable to disconnect it from the drive.
-
-
-
Disconnect the power supply control cable from the power supply.
-
-
-
Use the tip of a spudger to disconnect the fan cable's connector from its socket on the logic board.
-
-
-
Use the flat end of a spudger to disconnect each of the four antenna connectors from the AirPort/Bluetooth card.

Where can I get this S-ATA cable. I bought an Apple iMac 27 inch with 5K display in a BTO configuration with 1 TB internal SSD (flash) and NO internal HDD (classic drive) and would like to put a big (like 6 TB) disk in it. After opening the iMac I realized that the S-ATA cable (mentioned above) is missing. Any hint to a source is appreciated.
Hi, are you sure that is the same cable? i have the same question, because there is says its a replacement hard drive power and data cable for the late 2014 through Mid 2015 iMac 27"
