You'll need a load resistor to simulate the load of the stock bulbs. The hyperflash is the stock system thinking the bulbs are burned out since LED's don't draw much power. Our flashers are controlled by the BCM, so there isn't any flasher unit to replace.
That being said, I've gotten used to hyperflash, and I'm wiered out if I hear a regular flash speed.
