Hello,   recently I own a (used) Skoda Fabia Monte Carlo. I like it and I'm very happy with this vehicle. Now I would like to retrofit a multifunction steering wheel - only the keys. I've found a how-to for a VW Polo (http://www.uk-polos.net/viewtopic.php?t=54171). After changing the airbag wiring loom (part# 5E0971584A), I upgrade the two cables. First the LIN from BCM (white plug), pin 17 to pin 10 on steering plug and the second +12V cable from pin 15 on light switch to pin 9 at steeri
