I made this video to make things a bit easier because I seen someone say the wrong connections go together so here it is for the stock 05 g35 lows replace the old HID stuff with the OPT7 brand that come with spade connectors for the D2S & D2R it is the stock connection has 2 wires green & black and the OPT7 HID kit has red & black so it will just pair it black with black and then red goes with green. And this is my link for my video showing it. https://youtu.be/3bj5cwwJF0I

 

I just put these on a buddies Ford Focus.

For budget HID reflector kits these give people the look they are looking for! I mean it's like $40. But the bulb is not able to be replaced without replacement of the whole ballast...
