Sup guys and gals... I've been doing my WW clear fogs all day basically... one down, one to go! Anyway...

I have a HID kit for my fogs. The kit basically says to plug the factory power into the ballast and then from the ballast there is 2 plugs to plug to the wiring coming from the bulb. I did that, started the car, turned on the fogs, and nothing at all... I thought maybe both sides needed to be connected so I did that, still nothing. I'm kinda clueless...

Do I need to run wiring directly from the battery to a relay and get power from there?

Any help is greatly appreciated!

Reverse the polarity of the plug. If the ballast is getting the reverse polarity, it won't fire. I ran into this problem when I was installing my HID's too.

I CAN try that... But the plugs are all a one way fit I'm pretty sure.

It's the kit. They are all made for japanese cars. Both of my HID kits were like this.

Hahah I had the same thing happen to me. Thought my HID fluid was low but it turns out I just needed to swap the wires! LOL!!

My kit came with 2 extra wires and a little sleave to do this.
