Speedo system wiring diagram

[Apache]

Anyone have a link to one, just so I know roughly where to look when sorting out my non-functional speedo!

Started misbehaving near the beginning of the big trip, accompanied by the flashing OD light telling me that the ECU is getting no signal from one of the two gearbox speed sensors.

The speedo has come back once or twice so I'm assuming a bad plug / poor connection somewhere.

When mine did that, it was a track on the spedo PCB that had burned out.
