Which dash kit is that? Also, please tell me more about the buttons where the shifter would be on regular exp and the cup holder right below it.
The dash kit was "Metra 99-5828CH 1 DIN/2 DIN Dash Install Kit for 2011-UP Ford Explorer". It was designed for analog A/C so if you have a smarter one (like the one setting up temperature, this kit will not work unless you re-programmed A/C module with ForScan). The kit cost almost 300+ MSRP but I got a used one from eBay well under $100. The touchscreen is an aftermarket I teared down from my previous car, without GPS.
I installed it with "Metra XSVI-5524-NAV Retention Harness Ford 11-Up". Straight forward installation. Soldered the harness with the pigtail comes with the touchscreen unit, then everything is good. I also have a wired backup camera, and the harness already pickup the backing signal from the car, makes that plug and play too. I believe the harness also support OEM GPS antenna (since they have a blank connector for it) but I don't have one, so I have no idea how that works at all. Just be careful the space will be very tied for all those wires so get a tube to keep them organized. One of the disadvantage is that the media control on the steering wheel doesn't work with my touchscreen, I had to add an addition wireless remote to make it work (that's why I have tons of motivation figuring out how to convert the media control to aux buttons, and still no luck yet).
The center console was from a retail Explorer (probably 2016?). I removed the floor shifter since it is useless for FPIUs, and put in a rocker switch hold so I can get some good looking switches in. It is "AutoEC Rocker Switch Panel Switch Holder Housing Kit" (I think any generic switch housing will fit) you can also get from Amazon, and some random switches. Because the floor shifter is completely removed, I have tons of spaces within the center console, and I built a power distribution panel into it so I can play around with (by the way, all lighting and power outlets on the center console are live, except the rear A/C control, which my FPIU doesn't have). All the power came from the police connector in front of the center console, and turns off when the engine shut off (and that 12V switch you see on the pic, that's the override switch so I can choose to have the equipment running when engine off, and a voltmeter reminding me don't drain out the battery). I've also added front and rear fog light controlled by the switch (two stages switch). I was planned to route the fog lamp back to the BCM so I can use the OEM switch, but found out the console is easier to reach.
I will see if I can find some more detail photos (I took a lot of them during installation for my own reference, just not sure where I throw all of them). Will upload when I found them.

(It was a mess, since I used quick connectors to test the harness. The wires are now soldered permanently looks better organized).
