Tacho install 1964 1000 MErc

[stuee]

Hi, i want to add a tacho on my motor but cant work out where,
I have attached the photo of the wiring diagram from the motor.
I gave looked around and only seem to find info one the next model up with the switch box.
I know on a car you attach the tach on the neg side of the coil but mine has 2.

Anyone help?

thanks

one of the yellow wires from the stator going to the rectifier. usually there is a wire going to the remote but I don't see one on your diagram.
