Does anyone know the radio wiring color codes for a 1984 Chrysler Fifth Avenue?

The wiring diagrams below are not correct. You only have 7 wires running to the speakers somehow on this model. There are 5 on the black connector and 2 on the Grey connector. The best way to wire this car is to go ahead and run wiring straight from the deck to the speakers and bypass the connectors, but go ahead and buy the aftermarket connectors from Wal mart, just don't use the speakers.

Perhaps this color code chart can help:
12V battery wire: pink or pink w/white stripe
12V ignition wire: red w/white stripe
Illumination: orange
Power antenna: white
Dimmer: none
SPEAKERS
Front left(+): dark green
Front left(-): brown w/red stripe
Front right(+): purple
Front right(-): blue w/red stripe
Rear right(+): blue w/orange stripe
Rear right(-): blue w/white stripe
Rear left(+): brown w/blue stripe-br /> Rear left(-): brown w/yellow stripe

Answer

Chrysler vehicles have two connectors for the radios. The connections are viewed as looking at the front of the plug with the wires exiting the rear:

Gray connector:
1 = 12 volt battery / constant
2 = 12 volt ignition / switched
3 = Radio light
4 = Memory light
5 = Right Front negative (RF-)
6 = Left Front Negative (LF-)
7 = Not Used

Hold the connector in your hand with the little tab at the top pointing to your right and count up from the bottom.

Black Connector:
1 = Right Rear Negative (RR-)
2 = Left Rear Negative (LR-)
3 = Right Front Positive (RF+)
4 = Left Front Positive (LF+)
5 = Right Rear Positive (RR+)
6 = Left Rear Positive (LR+)
7 = Power Antenna

Hold the connector in your hand with the little tab at the top pointing to your left, and count down from the top.
