Schematic for my HID lights.
The relays follow the original lights at all times, the HID's are switched after the fact. The high beam lights follow the OEM lights. You dim the beams, the HID driving lights go out. The fog light switch is an override. It makes the HID converted fogs stay on at all times, instead of going off with high beams. (As per original Jeep design) With the override switch off, the fog HID's go off with the high beams turned on.
Mounting for the front set:
Aluminum angle piece with braces underneath. The lights are more solid than mounted to the plastic trim.
HID ballast buried under the little headlight access door.
Set of HID light relays.
The fog light relay center tap. (As noted in the schematic) My extra added white wire is soldered to the center terminal.
