Tom_16v - sorry i did miss it off, cant seem to edit my post though. Oh well. Yeah the wiring is pretty easy (even i managed to do it). You simple connect one wire from the 3rd brake light to the current brake light wire, and earth the other one (theres a point in the light cluster already). Pretty simple, i like the spoiler, it matches the lines of the car well, it looks particularly good on a lowered car too.
