A ballast went bad on me and I realized that the previous owner didnt have matching HID kits on the car. One side has a female connection with 3 slots while the other side, and the new ballast I ordered, only has two. They look as follows;

The one on the right is the one I need to replace to connect my new ballast. My question is this a proprietary part with certain aftermarket HID kits or should I be able to get this part fairly easy somewhere in my city? I need my headlights fixed immediately, Ive been pulled over once already.
Thank you for your help.
