Stereo installation - support needed

Hi all.
It's my first post here.

I bought an android car stereo on line and I need your help.

Is there a drawing that shows what is each wire ?

If the new head unit has a different block pattern, you should be able to buy a wiring harness adapter. I think mine was around $20 and saves a lot of hassle.

+1 to a wiring harness although if it's a Chinese no name brand it might be a bit difficult to get your head unit to Toyota.
The other option is Toyota to bare wire and hopefully your new head unit harness to bare wire.

Then you just need to match the bare wires up. I'm sure Google will tell you what wire is what.
You'll have at very least:
Constant +ve
Ignition +ve
Ground
Front Left Speaker +ve
Front Left Speaker -ve
Front Right Speaker +ve
Front Right Speaker -ve
Rear Left Speaker +ve
Rear Left Speaker -ve
Rear Right Speaker +ve
Rear Right Speaker -ve

On top of that some have extra functions and those functions have extra wires. Antenna Trigger wire, remote signal wire (turns on amps with ignition), etc

Hi all thank you for your help.
I used an adapter but only not to cut the original connectors.
The head unit itself came with extra connections and i had to improvise.
For example:
GND-
GND-
KEY GND

I connected all to the ground connector.
By the way in Toyota the ground cable is brown.
The was initially my mistake connecting the ground to the black cable which is antenna power.
Due to no reception I understood that I have a problem.

Now it's seems to work but I'm waiting for extra reverse cam and USB extension to finish everything so I left the system from the external part of the panel.
There are so many connections I hope it will still fit.
