Pull out the passenger AC vent near the door (align the vent to see the place where you stick a screwdriver to lift the pin, quarter turn to the side and pull gently), push out the side panel that has the ' rear mount baby seat will become a projectile if the airbag goes off' sticker and there is a foam covered hole there that pushes through the top top back of the engine bay under the cowl to the side where many people have dented when letting their front door swing wide without the stop strap.
I use about a metre of straightened coat hangar to push through a couple times before attaching the wire thats going through the space. I think I have 7-8 cables going through there currently.
