So I reversed the connections on Tail and Park, and now everything seems to be working as it should. It makes sense, and that's how I should have wired it to begin with. I think the instructions I was following have a typo, because the way I originally did it was the way it said. Should have went with my gut. Also I put the Instrument panel lights on the unlabeled terminal, because that gets 12v in both switch positions.


Almost there, now I just have to figure out why I have no brake lights and no rear turn signals. I have front turn signals, so I can rule out the turn signal switch and flasher I guess.
