I have been reading this thread and doing some research. As of this morning I was ready to pull the trigger and order the retro kit from lightwerkz until I saw the kit from fastheadlights and noticed there is not a relay harness. Can anyone tell me why that is. I really want to do a retro fit with hid lights but want it to be right. Also is it worth doing 50watt ballasts over 35watt
