What does MFI speed/rpm sensor look like ?
 

I am trying to locate the rpm/speed sensor on my 73'. The diagrams I find show a round metal part about the size of a C cell battery. Is this correct ? I could use a visual if possible .
Thanks

On my 69, the sensor looks more like a small silver rectangular box.
It is bolted to the electrical panel on the left side of the engine compartment.

RPM Transducer
 

I thought that was the part in question. The box relay has been referred to as the RPM transducer in my sources . So I guess the description was the source of my confusion .I viewed a relay panel diagram that showed the round part described as "speed sensor " . That is the problem with Haynes type multi year info when you are trying to learn this stuff .
I wish I could find year specific manual for reference but per Bentley website they dont offer it. Thank you for the help.
