I recently purchased from ebay a 00 BCM (Body Control Module) for my 99 sierra. I have been told that this swap will clear the airbag light on my escalade cluster and I will be able to turn the drl's/headlights off with the cargo light switch or dome override switch. Has anyone done this swap and do they have any probs when doing it? I have an HPP III also that is currently installed, but I think that it reprograms the PCM. I am going to return the PCM to stock setting just in case there is a problem. My plan is to uninstall the hppIII, disconnect the battery, swap out bcm's, reconnect battery, program the bcm to the truck's r-code, and then re-install the hppIII. Just curious if anyone has had any issues. Any install suggestions would be helpful.
