See the video in the link.
At the risk of getting too far off topic (but related to the Dive Plane installation), since I removed the bumper (twice) I thought I'd pass on a couple observations.
I used the service manual guide for removal. You really only need a T15 torx bit for the dozens of screws and a 7 mm box end wrench for the bolt that holds the bumper to the fender . Very straightforward.
The tricky part is disconnecting the wiring harness. The attached video shows how it is disconnected. It's tight access even with all the screws and the clips removed and detached. You will see only the end to the left in...
On the CT4 there is an identical socket mounted on the top left shock tower in the engine compartment that is easy to access that you can practice on, if the CT5 has the same thing.

The real PITA is getting it reconnected on the install because there is little room to reach around it to work the latch. My wife helped as I held one side and she pushed the outer collar on and activated the lock.
