auto dim central mirror (module A22) calls for a 10-pin connector... if you have the 10-pin connector, it is a good start... next thing would be to look at the pinouts of the 10-pin connector, to see which pins are occupied and which are not, if any...

there is changeover in wiring in 09/2003 but it seems to be affecting the Japanese models... hard to tell from the available info...
