Fitting an Electronic Instrument Cluster
Technical information
Vss supplys a square signal. 1.3889Hz/ Km/h or 5000 pulse by Km Let’s make a variable frequency generator in order to simulate the speed.
Components needed
A power supply (12v) A NE555? A 10µF capacitor (C1) A resistor of 200 Ohms (R1) Another resistor of 560 Ohms (R2) with a LED 20mA (D1) (optional) And a variable resistor (range 0 – 10 KOhms?) (P1)
This is the schematic :
Built :
And connected :
Now you can wait until you arrive to mileage you want. Enjoy!!! or play with it
Fitting
First thing, remove the airbag management off the new one, and adapt it to the old one to prevent the airbag warning light being constantly on. Look at the small card, and cut the wire which goes from the pin 5 and from the airbag warning light. Then join pin 5 to the warning light as it’s done on these pictures.
Then remove your old instrument cluster, look at your plugs, on the longest, run a permanent 12v (otherwise each time you will put 12v your needle of speed will jump) to the pin 7. I took the wire from the cigarette lighter but you can take it from another source like the radio
Last modification, now look at your shortest plug, run a new wire (VSS signal (vehicle speed sensor)) from your AWS unit or your trip computer (otherwise from your engine bay) to pin 6. Like it’s done on this picture.
Finally plug in the speedo, check you haven’t blown any bulbs and enjoy!!!!!
That's it!

Extra Addition
What if I have neither an AWS or Trip Computer You need to run a wire from the big plugs near the airbox. This wire needs to run from pin 2 shown below:
