I might be able to help you with that. I can't remember the exact pin number. But, there should be 7 to 11 pins that need to be connected.
3 is for power and 4 or 8 is for speakers.
3 pins to:
power (12V)/memory/battery
ground
acc pin.
4 to 8 pin:
FR,FL,RR & RL positive and negative terminal.
But, I am not really sure your player can support RL & RR. I have tried that on my HU (iswara SE) and actually it only has front. The rear one must use amp (RCA).
I will get back to you regarding the exact pin location once I reached home :D
The other way is to check back the original wiring at your car. If you can see the socket and wire, I gues you would be able to see few wires is not actually connected. These are supposed to be rear speaker out.
Check the wire colour on your speaker at the rear of your car, then you would get the idea of which is FR+, FR-, FL+ and FL-.
The 3 more wire that is left would be for the 3 power connections.
Black in colour is ground.
Which leave you with 2 more wire. Both should be connected to 12V.
The only thing is, one of it should be supplied with constant 12V. Meaning, must always have power. This is to retain the settings you have made to your HU (radio stations and stuff).
Unless you don't need to retain your setting, this can be connected to the 12V on/off too.
The other one can be connected to an on/off switch that supplies 12V also.
By the way, If you wanna connect it at home, you do have a voltage converter that will convert the AC voltage from home power supply to DC 12V right?
