Signals not flashing after Atari delete modification

I just finished the Atari delete (got the speedometer working lol) and now I am running into the issue with my signals not flashing. The turn signal switch still activates then they just do not flash any more. I had upgraded to the led turn signals so I was using a electronic flasher. Is it likely that that might of gone bad ? Would another wire need to be connected in order for them to flash with removing the Atari ? I’m leaning towards a dead flasher cause it would seem like if I missed a wire the turn signal switch wouldn’t activate them am I correct in thinking that ?
