    Ive wired mine straight into the light cluster. I did on my last S3 too. Had no problems at all. Only when the wiring was wrong the trailer end. Even then the dash just tells you that a bulbs out. Your supposed to use a relay in there but ive never bothered. I tow every other weekend with no probs and have for the last 4 years.

    should use a 'smart' relay as this will stop warning lights coming on the dash, for the money they cost its worth fitting one

    and to answer your first part of the question, yes, im a towbar fitter

    you'll more likely find that the plug and play ones have a control unit with them, rather than a seperate smart relay, hence the need for the live feed wire

    its mainly down to cost that most ppl tend not to go for the plug and play option, even tho when you do the maths, parts + labour theres not much in it
