This is such a hard thing to troubleshoot that I am pretty sure no one over the internet can help, let alone in person. Since you swapped all the wiring, engine, etc, you are probably dealing with quite a mess. So I can't even come up with a thought of what could be wrong other than the wiring is messed up and not hooked up right. Something really sounds fishy when you push the horn and the lights come on.

You mention swapping the interior and engine.

Let's elaborate. Did you swap the dashboard and dashboard wiring? If you did and didn't change the wiring beyond that, it's possible the wiring doesn't line up in the connectors.
