Is there any issues with Hyper flashing when connected to the turn signal? I know using some types of LED lights in modern trucks can create hyper flashing which requires a separate relay. Are there any other components required for a proper installation? Thanks!

Normally there are no other components needed or to add. If you are using LED's for your signals and tail lights, you may not have enough resistance, and need a LED specific flasher relay. However, if everything is working now, the headlights should make no change to the system, or flash or flicker.
