Hey y'all, i got 08 uplander and i think the bcm has gone out on it. I can't find an electrical manual for it though, or even just a diagram of pin assignment on the bcm. I'd really like to know which pins for sure are primary voltage in and ground so i can make sure everything's good with those before just replacing the bcm. Any help would be appreciated

 

have you tried alldata or chilton?
those are the only manuals i know of.

 

Here's the power schematic for the BCM.
