For all your guys out there driving without your speedo, and more importantly your tacho, at night.
Got mine working nicely a while ago, so good luck.
- Warm up soldering iron.
- Remove top part of dash. Don't forget the nuts on the wiper and lights switches.
- Take out lights switch.
- Pull apart the switch and pull out the little circuit board at the back.
- Re-solder all the connections on this board. Don't add wires or change the connections, just add a bit of new solder and make sure all the connections are good.
- Put back in and check it works, then blame me if it doesn't.
