tillithz/Batman, are you sure you the info is for V6 model, not a I4 model?

thanks all for your input! I found a service manual for my car yesterday. It shows that ECM applies to M/T and for my car, which is a A/T, a PCM unit, which is located underhood, is used instead. The closest location seems to be a blue/white wire between the PCM and the speedometer, which is behind the dash on the driver's side. Anyone has any ideas about this PCM thing? Another thing I am think is that if I can use the cruise control unit, which is close to the gas pedal. do you think some wire there can provide speed pulse? thanks. QQ

bobby121687, but why are others talking about hooking up speed sensor? can you be more specific to why I shouldn't?

Batman, I am planning to install a D3 to replace factory stock 6-disc cd changer, could you please tell me the location of speed sensor cable and backup light cable's nearest reach point from the stereo unit? thanks a lot! QQ
