This will only
work with the same wattage bulbs as those from the factory.
use the factory fog light harness alone to power up higher wattage lights, you'll trip the circuit. If you use an aftermarket light, it must
be the same or less wattage as the factory fog light for you to wire to the existing harness for power. (i believe it is 55W maximum, someone correct me please if i am wrong)
That being said, you CAN
however, use the power wire from the factory fogs to trip a relay that sends power to higher wattage lights. This is exactly what i did. I added KC fog lights in lieu of the stockers, and tapped the power lead for the stock passenger front fog light to trip the relay for the KC's. This way they work with the factory stalk switch.
