need wiring diagram for 2007 suzuki reno

I bought my brothers cd player out of his 2007 Reno after he totalled it so I could retro fit it into my girlfriends 93 Beretta. The problem that I am running into is the wiring. It has an 18 PIN connector that I am not quite sure where everything wires up to. I know the speaker wiring because it says it on there but others are just confusing. This is a list of what is on there...........

1.Front R-Ch (+)

2.Rear R-Ch (+)

3.Illumination

4.Acc B+   ??

5.Back-Up B+   ??

6.Phone Mute  ??

7.Rear L-Ch (+)

8.Front L-Ch (+)

9.Front R-Ch (-)

10.Rear R-Ch (-)

11.Illumination (-)

12.Auto Ant B (+)   Don't have a power antenna so I don't need this one

13.Remocon Ground  ??

14.Ground

15. N.C. ????

16.Front Remocon Data  ???

17.Rear L-Ch (-)

18.Front L-Ch (-)

If anyone can help me out I would be really appreciative.

Acc B+ = Switched 12 volts.  This wire turns the radio on when you turn the key on.

Back Up B+ = Constant 12 volts, this wire needs 12 volts on it even when the key is not turned on.

N. C. = No Connection

Phone mute mutes the audio when you are on the cell phone, if your cell phone has a mute output wire. 

Disregard the remote control wires.
