This is the case with my conversion, which was finally made right. It formerly utilized a poorly hooked up 240D speedometer that was horribly inaccurate, and now it has a correct 300SD speedometer. To make it work though, Kurt had to invent a new signal generator by welding four magnets onto the drive shaft and attaching a nearby sensor, completely hand wrought. It works great, but nearly self destructed in the first two miles due to faulty clearances. The magnets are still bent over from the initial snafu, but work just fine. What a noisy racket that made!
