I would also like to add that I went to the local Chevy Dealer and they printed off the procedure and gave it to me after I had a battery replaced at the local auto parts store (which is why the Keyless Transmitter needed to be reprogrammed).
The GM manual had a diagram of the ground connector in question that showed a 7-pin connector about 2" wide WHICH DOES NOT EVEN EXIST ON MY 99 LUMINA! The close-up picture
http://files.automotiveforums.com/ga...hp?photo=45853 earlier in this thread is what should be in that thing GM calls the "service manual"

. GM needs to look at who is writing their service manual diagrams and start using real pictures!
Also, can anyone define the Acronyms (abbreviations used) like "RKE", "CKT" and "RCDLR" for sanity's sake?
Thanks and great job in clarifying this mess!
