Here's my adventure on installing Pioneer AVH-4200NEX into '16 Civic LX Manual, using Metra 70-1731 kit.
First issue - After much questioning and read this whole forum on rear cam, I decided to troubleshoot this myself. Especially the issue that the logic (for view switching) is 8V and the Metra's XSVI-1731-NAV (with 6V converter + AWSC). We have quite a few who purchased that kit and it doesn't work. So the logic (per Honda's tech manual) is 8V, but Metra kit converts to 6 volts?
Point 1 - Camera power supply (Camera Vcc, pin 13 on the factory radio side) is actually 8 volts, not 6V. I measured this in situ while the car's ignition is on "On" and in reverse gear. I stuck a sewing pin behind the connector and ground to measure this. It may work if you connect this to 12V, but I'm not risking it.
Point 2 - Metra 70-1731's wires for the camera instructs you to connect the Camera Vcc supply to "Switched Power".

This, effectively, turns the camera on when the car is on.
I measured this Camera Vcc (power supply) while the car is in reverse (and yes, it turns on), but when I shift out of Reverse, the Camera Vcc goes to 0V.
So if you follow the above instruction, the camera will always be on, but you're just not looking at it. The head unit will switch the "source" to back up camera view. So functionally, it's fine, but the camera is always on.
My solution is less than elegant. I use 7808 (to convert from 12V to 8V) IC to supply the camera, and a (solid state) relay to turn on and off the 7808 (in turn, the camera) when the relay receives 12V "BACK LT" signal.
I'm going to install it this weekend. The harness is nasty as it has quite a few ICs on it.
Lastly, I contacted Metra and they sounded perplexed. They won't sell the pins, so I bought another kit and tore the pins out. You can do this by inserting a small flathead screwdriver into the pin side of the connector...push it as far as you can, and then pull the wire. You are depressing the tab by inserting the flathead, which allows you to pull the wire out.
