Hi !
The roof console (headliner ) located connector.
has the following paint wires:
Yellow - DLC (Data Link Communications)
Orange - Battery Positive Voltage
Gray w/Black - Ambient Air Temperature Sensor
Gray - Instrument Panel Lamp Supply Voltage - 1
Black - Ground
Brown
That's the connector you need. Just plug this connector into the DIC socket.
The mod itself will depend on the type of console you'll be able to find on E-bay, or somewhere else. The overhead console components are attached to the console with torx screws(the DIC and the reading lights. The switch assembly is attached to the console by means of plastic tabs). You may choose to retain the switches you already have in your vehicle, and put them into the new console, or you may choose to keep the new console switch assembly, even if it has features you dont have in your vehicle. The switch assembly will fit, since each of the blue and black connector wires have the same position, regardless of the equipment present in the vehicle. If you choose to retain your own switch assembly, you'll need a small flat screwdriver to pry out the old switch assembly out of the console (look for the corner plastic tabs), and then, you put back yours by pressing it into place.
After that, you'll have to look into the temperature sensor mod, if you want the temperature to be displayed. If you dont do the temperature sensor mod, the temperature displayed by the DIC will be 0c.
I suggest you to read
GregA. He took a lot of pictures of the mod, so you'll have a good idea on how to do the mod. The mod is easy to do.
