I'm switching the color of my seatbelts from black to red and aleady have the Porsche OEM parts. However wondering if this is a DIY job or if I should have the dealer do it. I'm relatively handy but dont' want to mess with anything that has to do with airbag sensors or the such.

If dealer install, what would be the approximate labor charge I should expect?

08 Cayenne GTS.

Thanks
