Yes you have to drill the bumber - but the holes are not cover - You have to be skilful to do it properly - then you needn't cover anything - my bumper wasn't even painted after this operation.

Cool. Reading the PDF, I see that you use a smaller 3mm drill bit at first, then bore it out with a graduated bit. That would indeed provide a nice clean hole.

Seems like a DIY project for those with moderate skills. Only difficult part IMHO would be doing the bumper drilling to get a clean edge.

After scouting out parts, and assuming I can use my existing control module, this appears doable for about $250 USD, excluding the coding. Very cheap if so!!!
