Nissan changed the head unit on '19+ model and I can't find the new diagram for the new 40pin and 20pin connectors. Does anyone have it? Thanks
Picture for the 40pin connector is attached. Please review

Thanks. Your info is pre '19 model with 32 pin connector. Nissan changed it to 40 pin on 19+ model.
Based on my research this 40 pin connector is reverse camera, steering control, and speed sensor, etc.

Hello, I have a 2018 Nissan Altima with very similar radio and wiring, see pictures, can you help me identify the audio power etc. wires so that I can add an aftermarket system?

the 20pin handles the radio power ground acc, speakers, vss wires.
a standard 20pin Nissan harness will work for that.
the backup camera and steering wheel controls it doesn't seem anyone knows yet. they come off that 40pin connector. I have it limited down to the group of 4 that are 2 blacks, a red and a white, go to the camera but I don't know which is which as I already removed the factory unit and installed my pioneer and I can't find info on this anywhere.
I'm about to give up on it and install a standard 12v backup camera.
oh yeah that's another thing, for the camera you will need the axxess 6v converter or a similar buck converter as Nissan apparently lost their minds and decided to power their cams with 6 instead of 12volts.

with the help of axxess support I got everything figured out except for the speedsense wire.
well... and the aux in, but honestly that would be incredibly easy with a multimeter I just don't care about that because I'll never use it.
anyone know what wire the speedsense is and which harness it comes from, the 40pin or the 20pin? I don't know if i have any extras on the 20pin or not...

Can you post the information Metra helped you with? Wire colors and where they went. It may be helpful for someone in the future.
