ok guys, did this last night at my work parking lot, using my spoiler stop light, so i have it wired in mode 2, also took my spoiler down and wired it in there, splice some wires and made some extension wires so i have more play, and mounted that module in the spoiler with double stick tape. easy mod, might be the first 4th gen to have a blinking high mount stop light

and this all costed me 35 bucks.
