You should be able to trip a relay off of the factory fog light circuit to control the new lights from the factory switch, but I'm not sure how the CANBUS would feel about not having lights plugged into the factory harness. There are also anti flicker harnesses if you wanted to try running the new lights right off the factory harness and have flickering. Good Luck!
