There is already a wire bundle there that you can tie up to with zip ties. The only problem I had was in getting the a pillar cover back on straight (that and a couple fingerprints on the cover...), wish I had just tucked the wire in rather than pulling the cover and tying it up neat.....Slider said:For those who have installed this on a B5.5, where do you run the wires after they exit the headliner? I guess I am wondering whether the airbag in the A-pillar prevents you from running wires under it? Would/could the wire be an issue if that air bag inflates?
