Current ST cluster installed. Remove negative on battery and tilt steering wheel to furthest downward setting.
Remove 3x screws from plastic shroud using T-20 Torx bit.
I used a small flathead screwdriver to pull the top part of the shroud down so I can grab a hold of it. Pull towards yourself until it almost comes out. The two remaining retainer clips at the bottom of the shroud require you to pull from the very bottom in order to not break the plastic clips. Very much like taking the two bottom clips out of the grille assembly when removing that part. Take your time and it wont break.
In the lower right hand corner of the picture you will see the housing for the retaining clip mentioned in the previous step. There are 2x screws to remove to allow the cluster to be moved freely. They require a 7mm socket driver or 3/8 inch driver. Once removed, tilt the top of the cluster towards the front of the vehicle until you see the bottom of the cluster and pull towards yourself.
Remove 3x connectors from the back of the cluster. This was a pain because of the tight space but be patient and careful and it wont take too long.
Remove old cluster.
Replace new cluster into the housing and make all connections. Push, Click, Push to ensure a solid re-connection.
Reattach negative to the battery and proceed to check all indicator lights for proper functionality. The gauges all work after the installation (truck was not on when I took this picture though). As you can see in the picture the DTE, outside temp, and the current radio station display are all functional. I can switch between the mileage, trip A, trip B and engine hours display on the bottom part of the EVIC but without the steering wheel buttons I cannot advance in the menu.
Re-intall the 2x 7mm screws into the lower clips of the housing and re-attach the shroud to the cluster housing. Screw in the remaining 3 Torx screws to the top of the cluster housing and the swap is complete.
