+1 on this. The universal electronic flasher has two plug connections. You only use the one that replaces the Honda flasher and you do NOT plug the Honda flasher into the other one. It's not a jumper.I just recently installed the same thing on my 2017. I remember the instructions saying to completely remove the original flasher and not to "piggyback" them (I think that's what it said). Is it possible you did that?
