The light should connect to the ballasts in a plug and play manner, you shouldn't even be able to mess them up only one way they fit together and the other half connects to the connector of the original bulbs that were in the car. Then find a good place to put the ballasts so they don't slide around or are in the way. I put mine under the headlights to the inside almost behind the grills. Also I would recommend putting some like spark plug or battery dielectric grease on them before you connect all the stuff because mine have gotten wet and they rusted. I had to take them apart and clean them and then put the dielectric grease on and it hasn't happened again. Hope this helps!
Thanks,
