hid fog light install, need help...

long time troller first time posting...

ok so i have been searching for weeks and im a bit confused about hooking up hid fogs. my car doesn't have any fogs but i already running hid lows for my headlights on a relay harness.

i just received my universal h3 projector fog lights and just ordered an h3 hid kit for the fogs. my question is do i need to hook up a second relay harness to get my fogs to run hid? is it safe or ok to run 2 separate relay harnesses, or unnecessary? i dont plan on using a switch im going to just wire them to the headlights.

any input is greatly appreciated...
