Problems with wiring new stereo.

[Auvity]

Hi everyone, I have a 2006 nissan navara with the stock PN-2649N stereo installed. Recently i bought a android radio that comes with correct color wires, but the stock one seems to me very strange. I installed many radios before but never saw something like this, almost all cables have same color. I saw this diagram online but the b/u that i suppose its 12 battery its missing or in other side.
If someone could help me i would appreciate it

I purchased an adapter for mine, from "Nissan to ISO Stereo" because my new head unit had ISO plugs on the rear. Is this an option available to you? Most places that sell/fit car audio systems will carry a range of adapter cables.

I found a manual with diagrams. My city doesn´t have auto parts stores so I will have to do it myself
