I purchased LED bulbs for all 4 turn signals and they hyperflash as expected. I also purchased an LED flasher relay to eliminate hyperflash. I could not find the stock flasher relay to replace, and now I read that the 2017 does not have a relay. So my only option now would the the resistor, correct? If so, would I need one at each corner (4) or just one each for left and right (2)? If I ever wanted to remove the resistor, would it be possible without damaging the stock wiring?
