I found the fiber optic cable ! It was behind the arm of the 3rd row seat. At first, I tried to reach as far as I can in the well until I touch a wire with some plastic cap on it's end. I took out the 3rd row seat and found it. Then I continue with my installation, after everything was hook-up including the wires, I put on some CDs and tried it. MCS did not recognized it . I double checked the install, it looks Ok, it has power (I can take out the magazine) but still unrecognized by the MCS. Now, I need to make an appointment to my dealer to have the MCS programming. I though the MCS would be able to recognized it but still have to do the programming ?

Thanks gilly for your help. Will keep you posted. Any update on the 2002 mud flaps ? That's next in my to do list.
