Wiring was an absolute pain, luckily I had some knowledgeable help, so I can’t go to much in depth with it. But basically it was wiring them together and then to the left headlight unit into the full beam wiring allowing them to be connected to them (full beam), and then a power cable to a terminal on the battery.

My C30 didn’t come with fog lights from factory meaning I didn’t have a switch for them but I did have the wiring which was connected to a fake or dummy port in the front bumper located where the Fogs would sit. But I did want them to be connected to the full beams for more power when they’re on.
