Process to wire up a tachometer

[GerhardP]

Hi everyone, 

Wondering if there is a how-to guide for installing a tachometer (going from the 2 clock setup on a Clubman to the 3 clock setup on the GT/GTS). 

Thanks, 

Vinay

Vinay did you ever get any sort of reply on this question?
I have also done some research and read(followed wiring diagrams ) but no clear definitive answer?
I tried one wire from the coil negative and one to ignition positive but nothing?
maybe a busted unit? maybe i broke it doing it like that?
Would be nice to hear if anyone has done this?
