Using the C10 connecting cable.

The picture below shows, how to connect power supply voltage to the dashboard controllers

of cars. The read lead (hot) is marked with (+) and the black lead (GND)

– with (-).

Solder the leads to the ST6249 dashboard controller according to the colours in the picture

below. The microcontroller pin No 21 should be lifted up (unplugged from its socket) or one

has to cut the printed circuit leading to that pin (the pin must not be short connected to the

ground of the dashboard (-)). After reprogramming of the dashboard controller the mentioned

pin cannot be re-connected (by plugging-in or soldering) because there is a pull-down resistor

inside the internal structure of the controller chip, which grounds the pin.
