72 Dart no turn signals or hazards

Hazards and turn signals were functional before I changed my instrument cluster. Now neither one are working. Installed an intellitronix unit and followed the instructions to the letter. Any idea on what would cause this? Hazard flasher is stock and turn signal flasher is heavy duty electronic unit for LED. All exterior lights were LED before the swap and dash is now LED as well. I'm going to reach out to them on Monday but would like to get it functional before that.
