panasonic wiring diagrams

Hey guys, i really need help.  I have a 97 accord sedan and i am trying to install a panasonic DP22 cd reciever in there.  I don't have the wiring diagram and i need it.  i try to match up the colors to the car but it won't turn on, its really gettin me upset.  There are two yellow wires, and two black wires.  I try different combos but it still doesn't work.  If anyone can tell me where i can find panasonic wiring digrams i would deeply appreciate it.  Thanks.

I don't want to be the bearer of bad news BUT..be very careful in doing your wiring. The colors on the car rarely match those of the aftermarket radio. Here's the scarry part..if your radio was grounded and you put 12V to an audio output, you could very easily wipe out the outputs. I would think that Panasonic would provide tech support and give you another diagram. I know that years ago before the days of the internet, you could just call and get wiring and schematics it sent to you. Good Luck!HotRod
