Next Time I'll follow Pauls advice
As Paul always says, buy a shop manual! I figured by talking to the Cadillac Tech that does the electrical work was just as good, so I tore the underside of the dashboard apart, only to find out that thats how you access the ENGINE control module, not the BODY control module. To access the BCM, you remove the glove box liner (6 screws) and the darn thing is right in front of you! Long story short, its fixed, the car operates as its supposed to and is now for sale so I can buy my next car!
