just one thought though, they dont really include any flexible conduit with it. i wasnt happy with how the wires bent over on themselves when you closed the door. eventually they will snap from all the opening and closing, so (and feel free to not do this cos' it is a little dodgie) i drilled a 8mm hole on the door and sealed it with a grommet, then drilled a 12mm hole on the A pillar and put a grommet in. then got a coat hanger and cut around 180mm and bent it in a curved shape which i wrapped into the loom really tight so it wouldnt move.
the idea is that when you open the door, the 8mm grommet and loom doesnt move at all, but the 10mm grommet allows the loom to slide in and out, the curved shape is the angle the wire takes when the door is open. making sense? so that way the wire doesnt fold over, it rotates in and out of the A pillar. the only downfall is that the 10mm side isnt sealed against the weather, so it may get water in it.
just a thought. you will understand what i mean when you get to that part
