Possible to convert speedo to cable drive?

The transducer doesn't have any earth connections it's a plastic encased unit. As this transducer is passive sensor it therefore has a single electrical supply in, off the top of my head that's from a D1s fuse14 in the dash fusebox, then there's a wire onward from the transducer to the instrument cluster.
Although not important, there is tappings in the instrument cluster to the EDC and cruise control ECU, if the vehicle has those items fitted.

As mentioned above the transducer can last a while, in my case still using the original, and if it does fail its not a big issue to replace.

that may be true but it still has 2 wires and the 2nd wire runs over to the reverse switch. i know this as i changed all mine! and yes your correct its fuse 14. not right now as its dark but if needed i can get under there and take some pics of the wires cant remember what one went what way but i know that it has to feed the reverse light switch when i first replaced it i cut the wires out and put a wire straight through left the old loom there just cut each end and had no reverse lights got under pulled the loom and they link through each other added a splice and put the wire on from the switch on the gearbox and boom lights with reverse again.

so i could stand corrected with it not being earthed i will say they share a live instead lol.[/QUOTE][/QUOTE]
