1996 Dodge Intrepid Help meow

What 97 diagram were you looking at?  I'm about 99.9 percent sure that the wiring is the same for both years for that vehicle.  If the plugs aren't cut, then you can always follow a diagram like this: https://carstereohelp.net/wireharness_Chrysler1.htm.

Even if the factory wire colors are different from what you might have seen somewhere, the plug pinouts are always gonna be the same.  That's why I suggest that if you're installing an aftermarket deck you should get a wiring harness (Scosche CRB0, Metra 70-1817, or equivalent).  Eliminates any cutting of the factory wires, and certainly eliminates the need for a wiring diagram.

If your plugs are already cut then the wiring should be something like these colors:

P o w e r
Memory (+12v Constant) RED / White
Ignition (+12v Switched) Red
Ground (-) Black or Braided Silver Wire
Illumination Orange
Dimmer (none)
Power Antenna Yellow
S p e a k e r s
Right Front (+) Violet
Right Front (-) Blue/Red
Left Front (+) Green
Left Front (-) BROWN / Red
Right Rear (+) Blue/White
Right Rear (-) Blue/Red
Left Rear (+) BROWN / Yellow
Left Rear (-) BROWN / Red

here's another set of colors I found:

BAT 12v >> Pink or Pink/White
ACC 12v >> RED / White
Ground >> *See Note

Power Antenna >> White
OEM Amp Remote >> White
Illumination >> BLACK / YELLOW
Dimmer (+) >> Orange
Dimmer (-) >>

LF Speaker (+) >> Dk.Green
LF Speaker (-) >> BROWN / Red
RF Speaker (+) >> Purple
RF Speaker (-) >> Blue/Red

LR Speaker (+) >> BROWN / Blue
LR Speaker (-) >> BROWN / Yellow
RR Speaker (+) >> Blue/Orange
RR Speaker (-) >> Blue/White

AGAIN, let me stress that you should USE A WIRING HARNESS!  If you don't use a harness I must insist that you verify all these wires with a DMM before connecting them.
