2016 Nissan Sentra, Stereo Diagram

Hi can someone help me with a 2016 nissan sentra s stereo diagram, I cant find the color codes anywhere. Im trying to set up a rca adapter for aftermarket speakers and a amplifier

Smart key? Bose?

They don't have bose so I believe smart key

Do you have to insert a key into the key cylinder and turn it to start the vehicle?

Yes I do

Would anyone happen to have the stereo wiring diagram for a 2016 Nissan sentra? No nav, push button start SV model. Previous owner cut the factory harness. I am trying to install an aftermarket stereo Shelter in place; shelter with bass

Should be same as listed above. Did you check to see if you had the same colors?

It does but i have an extra yellow,also a black, a violet and a gray unaccounted for. I found the 12v yellow and ground new stereo to chassis but can't seem to get the radio on. Ive tried connecting the switch wire to different colors still nothing. Thanks in advance. Ps. Previous owner said it used to only turn on when headlights are on. Trying to get everything wired the correct way.Shelter in place; shelter with bass
