I'm going to bring this back from the dead to ask a question.
If I were to go this route and modify the D2S bulb to fit the D3S socket (I will keep searching to find how to do this as well), I know I would need D2S ballasts to go with them as well. Knowing that, will the wire that is built into the housing (where the truck harness plugs in) fit onto the D2S ballast as well, or is that a different connection from D2S to D3S ballasts? If it will, great. if it wont, how would you plug the ballasts into the harness?
