Use the stock coolant temperature probe in the thermostat housing, there are two of them really, I can't remember which one I used... and so I'll have to figure that one out (though I'm almost sure it is the upper one) as I will be going megasquirt on this next one.

The wire color in the stock 2002 harness is brown and white and the stock 325i harness is brown with a violet stripe. You can splice into the large firewall plug for this and you "should" have good results.

The temp reads normally with the stock e30 probe.
