To verify you are talking about your last car, correct? Because the Sport and GT both use the same headlight assemblies, if I recall. The difference is the bulb vs. HID part. The projector part is the same.
So with our car, it should be a lot easier, according to my research.
Yes, I'm talking about installing a kit in my Contour, the headlight housings weren't a great match for HID.
If the MS3 Sport uses the same headlight housings as the GT, with the same projectors, that would make the results of do-it-yourself HID much better.
