Installed a wireless charger in my console this weekend.
I wont go in detail on the steps as most know how to do it, but when putting the plastic tray back in I used 4 screws to mount the plastic tray back in place. The tray does still sit flush, and has no visual difference or feel than when 6 screws were in. I have used this over the weekend, and it has easily picked up the phone each time it is set down, and remains charging as long as the truck in on.
Below is the charger I used. To access the wireless coil, there are 4 rubber feet on the bottom that you need to remove. This will give you access to 4 screws. Once they are removed simply separate the top and bottom and the coil will come out. https://www.amazon.com/gp/product/B017KQXO4U/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1
