Gauge cluster M3 ( oil temp) 323ti
 

I think buy a M3 gauge cluster for put in my 323ti, because have oil temp.
Some doubts:

-The rear conector cluster is the same?

-If I bought one cluster with odometer in miles I can change by kilometer correct?

- To make oil temp work, I need to connect a wire to pin #13 on the back of the cluster? (if I'm not wrong in the original cluster of m3 is in the #13, but in the 323ti?) - I need the sensor, pass wire in the sensor-> ?big black round connector?fuse box? -> cluster

-The speedometer will go indicate correct or the sensor or calibration is differente?

-I need also a cap filter oil with conection of oil sensor =)

Someone already make this?
