250SE tachometer

I am putting my 250SE cabrio back together and find that there is no tachometer cable and no place for the tachometer cable to connect to the engine. There is a bolt on the block where I would expect the connector to be. The tach that came with the car has a female connector for the cable.

I read on the Pagoda site that one difference between the SE and SL engines is that the SE does not have a tach but obviously that can't be correct. Does the SE have an electronic tach or am I missing something? Some parts books show the tach but no cable.

Assuming you have an M129 engine, the tach drive is located just below and forward of the #1 spark plug. It should look like the one in this pic
