Assuming everything is back to it's original place and you didn't inadvertently sever a factory-made connection, have you confirmed the fuse on that circuit didn't blow at some point while you were making your modifications?
Both of you get today's "Genius Award"! While I did get some voltage out of my cheapo meter, that was after several erroneous meter settings. I also wiggled wires clipping an unneeded wire tie I'd used in the old arrangement. So, I did check fuse C3 on the passenger side fuse box and sure enough, holding it up to the light, it was severed. So I ran up to the auto parts store (running in the sense that I drove my Subby Outback there) and bought a pack of 5A fuses. Came back, pinned my wire to the pigtail, and replaced the fuse. Ta da!!! Let there be light!That's a good point. If you were poking around with a meter trying to determine hot and ground, or inadvertently pushed your hot and ground pins for the device in the wrong places, you may have blown a fuse.
Thanks for the help and pointers!
