something else...when you think you have things wired correctly and it is still not turning on, you can try reversing the polarity. this is easy, just reverse the plug going into the ballast. You just turn the plug 180* and plug back in.

Where you have the bare terminals that you plug into sockets, you can reverse those as well because you may have the power & ground wires mixed up going into the socket.

when i did my installation, i just left the car lights on, and just messed with the wires until i saw them kick on.
