Great! The only difference I know of, is the ABS connector can be different in older models, pin 4 for the 38pin connector and pin 39 for the 46pin one. The switch is the same part number for all leons 5f and the connection can be made only one way. You need extra power for the illumination of the switch and power for the ABS module. Nevermind, now it's working. I think that this is a must have feature on all FR models. Personally, I use it everyday!View attachment 24732 Oh yeeeess, finally the button works. I dropped off my vehicle at an automotive electronics professional and it works. The colors of the cables and the plans are completely different between countries. My car is Swiss, made in Spain. Nothing matches. I don't know how he managed to finish the hookup but it works. Thank you for your comments and your help
