Electronic flashers, unlike a mechanical flasher relay are polarity sensitive.
If you get no flash or a hyper-flash situation, create a couple pigtail wires
and swap the connections. This usually fixes it.

Remember if you have 4-way hazard flashers that's another relay that needs to be upgraded as well.
