Just a quick look I'm thinking check the steering column connector. See if there in the correct place. I'm just shot gunning it. I have no Idea what you did. The Ign 1 wire and the acc become hot when the sw is in the run position. The orange wire is the instrument lights. It might be feeding back through there.
Had a similar issue recently on a friends 68 GTS what we found was a corroded fuse in the fuse box not making good contact? Don't know why it caused the parking lights to come on but replacing the fuse fixed it?
