Hello ( As an example Touran 1T3 140 PS TDI ) After having long been annoyed about the eternal start/stop switch-off, a solution for the problem was developed. After switching on the ignition is switched off Start/Stop. The relay bridges the start/stop switch for 5 sec depending on the poti position. After pressing the button it is switched on again. 3 cables must be connected from the keyboard. 1. + 12 volt plug T18e/18 color sw/gr 0,35 qm 2. 0 volt staker T18e/ 9 Far be br 0,35 qm 3. Switch Start/Stop T18e/ 7 Color rt/gr 0,5 qm These 3 cables are connected to the board and finished.For the small circuit is enough space under the keyboard. Have fun making. Mfg Karsten
