Jdbug, you should really start a new thread.
As far as relay for ur headlight, there will be one input plug on the harness, plug that pigtail to the driver side headlight pigtail. Mount the relay somewhere and start routing your neg and pos wire to the battery, don't connect it yet. Route your power supply for the ballast, one to driver and one to passenger, for passenger I mounted it to the radiator sub frame. Connect the ballast power to ballast, install hid bulb, install hid bulb to ballast, install the relay harness power to battery, pos then neg. Turn on lights make sure it works. Sometimes if they won't turn on try switching the ballast power plug around because it may be reversed polarity. If they work mount the ballast.
The fogs are same way. The fogs should come with a pigtail to plug straight into the fog light power pigtail. Install bulb to fog, install bulb to ballast, and last plug power to ballast. Test the lights. If both work install ballast.
IF u need help. Plz feel free to pm me.. I tried to break it down barney style
