Navara Head Unit wiring diagram

[Emong3]

Mga sirs anyone has a diagram or knows the color code of the wires that comes out of the head unit?

Casa replaced the head unit of our navara with a GPS navi. I was going to install the stock head unit of the navara into our old civic kaso hindi ko alam ang wiring pin outs for the socket.

I tried asking casa hindi din daw nila alam at plug and play yung harness nila.

I tried connecting the red wire and the black wire to the positive and negative just to power on the unit however it did not power on.

Thanks sa mga makaka tulong...

2-wires are connected to positive, the main +supply, and the key-sensor "ACC ON" wire.(usually red or red-stripe wire). Without the ACC on wire, it would'nt power-up. If you could'nt figure out the signals, pry-open the the HU, signals are usually printed on the PCB.
