u can also run it around the bottom of ur door molding under the plastic covers, umm at least on my car u can, not sure about ur civic but should be the same, running it under the floor carpet is safe also u can run it under the passenger seat from the center console and right one back without making it visible at all just cut a small hole in ur floor carpet back under ur console thats how its done normally but u can rearrange it however u'd like TEHO, good luck
