I think the biggest advantage to running the wiring harness, is the fact that you reduce the amount current that is running through your fuse panel. While I'm sure most people won't have any problems running the lights through the stock fuse panel, just realize those panels weren't designed for the amout of current draw that halogen headlights require. The headlight harness is pretty cheap insurance to help avoid overloading your old fuse panel. A quick check to see if you are overloading the fuse panel, after driving with the headlights on for a while, stop and touch the fuse panel. It should be a little warm, but it shouldn't be to hot to touch. Just my .02.
