Hazard lights going crazy & more!

I need your help. I’m Getting the steering column reinstalled in the Duster. I got a new switch harness & ignition switch. put everything in, plugged in the harnesses And the flasher unit starts clicking without the ignition on. The rear hazard flashes even when the hazard button isn’t activated. I pull out the hazard switch then it flashes the front hazards? Turn signals work but are reversed when actuated? Any ideas? Did I get a bad/wrong harness? I’m so close to getting it on the road…
