Q. Is the speedometer an MOT testable item? Does it have to work?
I've just changed from a mechanical to an electronic speedo gearbox and replaced the petrol tank with a diesel tank and the matching instruments. (Don't ask!!!) All from the same van.
Is there a sub loom for the gearbox, (electronic) speedo and reversing light? All I can find underneath is a 4 way connector hanging loose. The reverse switch has two contacts and the speedo has three. The fuel gauge wire ends near the gearbox crossmember. Can't find any other wires. I have the wiring diagram, just wondered if there's anything missing?
