Ha! That's exactly what I did. I put a 1/4" hole just in front of the factory roof rack running on top of the vehicle. Basically right above the black trim that separates the front & rear doors on the driver side. I had some Toyota seal packing and sealed the fuuu***k out of it. I ran that down to the cabin fuse box area through the interior trim to hide it. I was nervous at first but if you seal it properly then it's all good. I can provide more pics if you need.
