Well, if the drawing in the other thread is too vague, best explaination is,
module is under the left side of the bread-box, passenger side, about the size of a ciggerette pack. Its the only thing in that area close to that size/shape.

Everything else as described is under the center display. Remove the bezel and maybe the top componant (switch/display board) and you will see all...
Taking the upper dash pad off gives some more working room AND better view. Look for all the phillips screws to remove bezels and pads. Bread box mounting is seen when top pad is removed.

Oz, what he's looking for is a good picture of the UTDS Module not the VATS Module. I don't have one handy and won't be home until Sunday.
