Using factory fog light feed wires

:
2016 and 2017 Grand Touring
I want to mount two LED fog lights on front grill and if possible use the two worthless existing fog light feed. How do I get to it and would it take the current of 18 watts ights?
 
Just unplug from the dummy connector from up top or from underneath removing the front under shield.And yes will handle 18 watts each.
