The following are the pinouts for this code (these pins are on the arduino UNO board):

Left blinker - pin 6
Right Blinker - pin 7
Battery warning - pin 8
Low beam (cluster illumination + fog lamp) - pin 9
High beam - pin 10
Speedometer - pin 5
RPM - pin 4
Fuel - pin 2 ( tested on BMW E36)
Temp gauge - pin 3 ( tested on BMW E36)

BMW E36 cluster dash pinouts (these pinouts are on the cluster connectors):

Power Pins:
Connector X16 white
Pin 22 & 23: 12V
Pin 24: Ground

Connector X17 Blue:
Pin 4, 5 & 16: 12V
Pin 3: Ground

Connector X271 Black:
Pin 3: Ground

For the lamps:

Connector X16 (White)
High Beam: Pin 1
Cluster illumination lamp: Pin 2
Right Turn Signal: Pin 3
Left Turn Signal: Pin 4

Connector X17 (Blue)
Battery Warning lamp: Pin 6
Fog Lamp: Pin 8

Gauges:
Connector X16
RPM: Pin 20
