2002 Dakota wire color factory stereo

I'm somewhat new at this, at least for this vehicle. I recently removed my amp and subs from my 1989 Jeep Cherokee to be installed into my 2002 Dodge Dakota SXT truck. When this stuff was installed in the Cherokee it was hooked to a Alpine CDA-7893 head unit and now I'm trying to hook it to the factory stereo in the Dodge. I have 2-12" MTX subs in a ported box and a Rockford Fosgate amp model # 3001. I need to know what the color (s) of the wires are and where they go (eg: acc, battery, etc.) I have it hooked up in the dodge right now, but when I have the truck running the amp is on and when I turn the stereo off there is a humming coming throught the subs. Between the stereo and the amp I have installed a L.O.C. which is needed for the amp to be hooked up to RCA's. I think I have hooked the amp power on wire to the wrong one behind the stereo (White wire w/red stripe). Can anyone help me with this problem. Maybe even point me in the direction of a wiring diagram for this inparticular vehicle's factory stereo color codes, etc.

Thanks a bunch.
