I have diagrams for lights, fuel, and fan relays. Sorry, no diagrams for fuse blocks. I did recently find a drain of my own. I knew it was coming from my Body2 fuse in the trunk. For a while I went without that fuse in, meaning no power mirrors, retained acc power, and no keyless entry. What I found...two wires were snapped clean. They were between the large harness on the left hand trunk wall and the small moving harness coming from the trunk lid. Hope that helps.
