Can someone tell me where to find the tach input for my '84 325e? According to the C101 diagram, the tach does not get its signal from any of the wires at that plug... I would imagine it gets the signal from the reference sensor in the bellhousing, but I am using an L-Jetronic harness... I'm lost 
Maybe I'll get an aftermarket tach or something...
