I've got nothing at the trailer connection. I haven't pulled the harness connector in the back over the spare yet and put a meter on it, but I'm on my way to do that. If that is hot, my harness from there to the back is bad, but if it's dead as well, where in the front does the harness terminate??

The owners manual talks about the trailer harness pulling power from fuse #22 (stop lights), but the stop lights work fine, so old #22 has juice. The 04 doesn't use relays, so that's not an issue.

Somewhere between the fuse and the connector over the spare is a hiccup. I'll check continuity, but does anybody else have any ideas?
