Altezza Gauge Cluster In An Is

[Josh300]

Okay, newbie here...I recently got an Altezza gauge cluster ( rpm on the left up to about 9k, speed in km in middle, etc). So I put it in yesterday but everything works except for the rpm and oil temp. I know the oil temp needs to be rewired but Im wondering why my RPM does not work? Does any one have a wiring diagram for the cluster or now how i can fix the problem? Thanks
