K11 Micra Coil pack Rev gauge install issue

[MrMiles]

Hey folks. 
Been trying to fit a rev gauge, I followed a video that has the exact same gauge but isn't working correctly. 
It has power and does it's little calibration when I turn on the ignition, but when the engine is running the needled does not move.
Videos show's what I mean.

Seems like the connections may be the wrong way round (possibly?)
