UCH.JPG

Connector PP3 Pin 2 -> earth
Connector PP1 Pin 1 -> earth
Connector PP1 Pin 3 and 4 -> 12V

Connector PE2 Pin 8 -> CAN High connect to OBD Pin 6 and Pin 30 on dash
Connector PE2 Pin 18 -> CAN Low connect to OBD Pin 14 and Pin 29 on dash

Connector PE1 Pin 7 -> to start/stop switch (short to ground for short time to Light up dash)

Beetwen CAN lines connect 120 ohms resistor.

Mbi, BIG THX!!!!

mbi : do you perhaps know which pins are the one to change what is displayed on dashboard ... so UCH would send the message to dash... to show km, consumption,...

Steering column switches are connected to UCH but If I remember well it's not clearly indicated on wiring diagrams which pin is used for this function and what signal.

Currently I have CAN emulator to check dash, show km.

when connecting on a bench, you should always use a resistor. working blocks are not always taken from the landfill. therefore, you do not need to blame yourself for incorrect connection to the pins
