error calculation module? Sounds like you mean a resister.I just got my hids from ddm and everything wired up great except for i didnt buy an error cancultion module. They had a wiring harness you have to buy also that is what i got. I think it was like 20.00 or so.
i will b looking into a hid light kit somtime soon. who has the best set up for the money. im not looking for those blue bulbs just A good nice bright white or a slight tint of blue if thats what it takes and will they keep my high low and fog light all on at same time when birights are on? thanks in advance
