Did you look to the left of here, in the Vehicle Wiring Database.  Last item listed in Car Audio and Mobile Video, Car Security and Convenience, or Cruise Control sections.  It is listed under the Cruise section.

sorry man,,i looked but did not find ,,but with your guide ,,i find i think what i need on this page h..p://www.the12volt.com/installbay/forum_posts.asp~TID~7197 for 2002 escalade ext,, should be the same,,the wiring: for :SPEED SENSE|dk.GREEN / WHITE      |   |ECM *3 (*3 ECM is located near the battery, down low, between the fender and the fan under the black plastic cover.) so i guess this is the wire that i have find,,and connect with my spped sensor wire thanks
