I should have said that, Peters comment got me all wound up.
On a slightly different but associated tack, as we all know, there are two water temperature displays, a guage and one on the speedo LED readout. Has anyone investigated whether it would be possible to wire one of these to an oil temperature sender, which could be tapped into the sump plug? Probably the guage would be easiset as it could be rewired quite easily I would have thought.
