I'm going to work on this over time but I have successfully used the Axxess/Metra adapters to put an aftermarket stereo in my 2019 Frontier retaining the backup camera and steering wheel controls. I understand there is another the 20 pin stereo connector that retains the steering wheel controls without having to re-pin the connector or program the buttons but I already owned the ASWC-1 from my old car. Also, since I purchased most of my gear from Crutchfield their tech support knows the Axxess/Metra products.

Philips Screw Driver
T10 Torx Driver
T20 Torx Driver
Crimping Tool Wire Stripper 2 Sewing Straight Pins
Almost all of these tools on the list are self explanatory except for the straight pins. Those are use to release the wires from the 40 pin plug. Any thin, flat, narrow object that will fit in the slot will work. The straight pins worked really well and by time I finished I was able to easily pull the pins out of one plug and put them in the new one easily.
I did use butt splices for the connections, while testing everything, but will soldier and heat shrink the connections at a later time.
