for the start engine is very easy to install. the tutorial is very long.
for resume:
There are 8 pins on the flat contact housing (start engine), but you only need 4 of them. 1, 3, 4 and 6.
Pins 1 and 3 control the illumination and 4 and 6 control the starter button.
on start button:
pin 1 : grey wire (wire of cigarette lighter)
pin 3 : brown wire (wire of cigarette lighter)
pin 4 : to the yellow switched (connector on photos 41. / 42.)
pin 6 : to the red wire (connector on photos 41. / 42.)
very simple!
