HID Fog lights

[CiviCity]

Hey guys,

So a few days ago, I bought H3 fog lights thinking that it would be pretty much a plug and play thing.
So today when I tried to install them, i got a few problems, thus why Im posting this here...

So firstly, the HID bulb is too long to fit in the OEM housing. What could I do to make it fit? I know that you can bake the housing and then open it to remove the small cover, but isnt there something
easier to do?

Also, where do I connect the 2 pins to make the connection of the light to the car wiring? I cant seem to find the positive and negative ports.

I need help or explanation on how he did this,
