Ok, I know there has been many discussions regarding this procedure and I have a copy of the TSB 93-68-9A.

However, the TSB has a diagram that does not tell any wire colors to help with the process.

So, has anyone here ever done this?

If yes, please tell me the wire colors that I need to attach the resistors. Photos would help as well.
 
If "SYS" is displayed in the LCD section of the instrument panel cluster after the customer installs a new (aftermarket) stereo, he will need to do the following:


1. Buy (2) 1 kilo-ohm 1/2 watt resistors. [Radio Shack part # 271-023. They sell them as a 2pk for .29 cents.]
2. Disconnect the negative battery cable.
3. Remove the receiver.
4. Connect one end of both resistors to ignition power. (Yellow wire in the car)
5. Connect the other end of one resistor to the purple/white wire in the car.
6. Connect the other end of the second resistor to the grey/black wire in the car.
7. Cover all connections and completely cover the resistors.
8. Reconnect the negative battery cable.


Maybe this will help.
