So the MGF has an electrical pick up on the gearbox....
I am looking at the ACEwell again and on their site they say this.....
Can the speedo operate with electronic gearbox outputs?
A: The ACE-3251, ACE-3972 and ACE-39xxB speedos can operate with gearbox sensors that switch between 0 - 5v and 0-12v. On some vehicles it is necessary to add a resistor or transistor to pull the output wire down to 0v in the offstate of the output.
For techy people: The models specified above can work with a maximum input frequency of 7KHz, other models can work with a maximum frequency of 100Hz.
If you need to connect a different model to a gearbox speed sensor then a 5v voltage regulator, ripple counter & output transisitor will be required. Alternatively, a speedohealer can be used as an interface.
