I have a Pioneer DEH-780, purchased used from a friend

I have the wiring harness attached, but no idea which wire does what.

I need a wiring diagram, a pinout, so I can install the sterio in my car.

There are 4 femae RCA jacks; two red, and two white. There is also a rectangular plug with 10 pins, two rows of 5 pins.
The rectangular plug has only 7 wires attached, some wires may have come out of it, or maybe it only had 7 to begin with. The wires are in this order from top right to bottom left;

X, X, X, Grey, Green
Black, Orange, Blue, Grey/Black, Green/Black

I was unable to find any useful information online, so I'm filling out this form as a last attempt.

I hope you can help me out with this.

Thanks,

Kevin Hyatt
