2002 oem stereo pinout needed

Hello, I have a 2002 Dodge Dakota pickup. Several months ago, my Daimler Chrysler truck stereo, P/N P56038589AL started to take a few seconds to change between AM and FM. The few seconds grew to be longer and longer until I would go without music for a couple of hours of driving. Then it stopped totally, except the clock still works.

I checked a bunch of things from ideas on the internet about a month ago and somehow it started working until I shut off the key and I haven't been able to get it going again. I tested all fuses under the hood as well as in the dash with a meter and they are okay. There is power at the two stereo fuses in the dash. I removed the stereo from the dash and metered the 22 pin connector for power. I have power at various points, but no power turns on and off with the ignition key which makes me think it is the wiring, not the radio. I don’t want to order a replacement radio and find out that the wiring is the problem. Various web sites on line have pin outs, but the wires on mine have different colours. I checked this site for the '02 and it showed the old 2 connector configuration. I checked it for the '03 and the connector looked right, but again the colours were different.

I am in Canada if it makes a difference. Here is what my pinout looks like, and again all power shown is constant.

1 pink/blk +12v

2 RED / wht +12 v

3 org –12v

4 wht –12v

5 n/a

6 n/a

7 light blu/vio

8 light blu/blk

9 light grn/grn

10 light grn/vio

11 blk –12v

12 pink/blk +12v

13 n/a

14 vio/yell -12v

15 n/a

16 n/a

17 n/a

18 wht/red

19 wht/ blk

20 tan/blk

21 tan/vio

22 blk –12v

There is also a tab for chassis ground, but no wire was connected to it.

Can anyone please provide a pinout so I can see if the stereo is actually defective?

Thanks, Paul B

Icearrow6,

Thanks for your reply.     The first three wires in your diagram are the same colours as mine, but the rest are different.      I'm not sure if I can assume they will do the same thing with my stereo.    If I can, then the #1 wire should be constant +12 for the memory which it is, and the #2 power wire power should be switched with the key, but it is constantly powered.   I didn't check to see if the #3 wire changed from -12v with the headlight dimmer, but the dimmer function of the radio works okay.

A friend told me last night that I should be able to use the pinout drawing for the 2003 Dakota from www.the12volt.com, because even though the colours don't all match, it does have the single 22 pin connector.     It is actually pretty close, but there are a few differences that make me doubt his theory.     I have an extra wire on pin 4.      That pinout shows #2 being the switched ignition wire like yours above, but since mine is constant +12v, wouldn't the stereo work with the key on or off?       The 2003 pinout also shows #'s 11 and 12 jumped and connected to chassis ground.     Mine had no ground wire on the radio body.     I just looked again to see if somehow that wire had disconnected itself and caused the problem, but there is no separate ground wire in the dash.

I think I'm going to need the exact pinout for my truck to check the stereo.   Thanks again, Paul B
