I ordered hid's for my fogs and lows, along with two relay kits.... i figured a relay kit would be two relays each (one for each side of the car) but nope two relay kits is just two relays. So, i put the kits in the fogs and i am holding off on installing the lows. Will i even need relay kits for the lows or will they work? i know i was told i need relays for the fogs.

You got it backwads you dont need them for the fogs you will for the lows but I put one on the lows and fogs to be on the safe side
This should help

"Just fyi incase anyone else has problems with the XenonDepot Fog Light kit on a '08. I had to reverse the polarity on the harness to get mines to work."

thanks for the help, time to grab a beer and see what i can do.

Yeah, had to do that too on my kit from marcel

What they said. Reverse the polarity, and one single relay for both lowbeam HID's.
