I upgraded my wiring harnesses to accomodate the higher wattage bulbs because some of the after markets 100+ bulbs would melt my harnesses. The new harness is a direct plug in and installs in about five minutes. I was able to notice the difference in clarity of the bulbs before and after it was done. I bought them through a local shop here in Orlando for about $50.. if you are interested I can get the details or give you the number so that you can order a set for yourself?
