Rev counter

[brainbug007]

After getting all the redundant wiring out of the loom and everything working except the lights and megajolt, it's just the rev counter I need to get working now. I've put the green wire from my edis into the right pin on instrument cluster (see attached picture) but when I run the engine the rev counter doesn't move I checked the voltage at the pin and with the key in position 2 and the engine off, it reads around 0.05v, with the engine running & idling, I get a reading around 0.35-0.39 (fluctuates). So would this mean the sierra instrument cluster handy andy gave me isn't compatible with an edis?
