Down the sides, under the carpet along the floor and door sills. I apoligize if it sounded as if I did the work myself. It was professional's. I saw the car at different stages of the work. I know they had problems of a tight fit getting wires for everything under the carpet and through the soft top storage well. I believe they used the existing wiring holes as I wanted no holes drilled unless absolutely nesessary. My crossover is under the parcel shelf. Very clean job.........sbr
