When I had my old 92 hatchback that was the way I installed the led mirrors was just through the headlights. Straight back on both sides.. Just make sure when you splice the wires that you give yourself extra slack from the headlight connector. Then I ran the wires under the fender and behind the door panel. I think that if you ran all the wires from the fuse box under the dash that would be more of a pain because you would have to pull up the carpet to hide all the wires..
