Rev counter test?

My rev counter is not working so my question is if I use a test wire from the back of the rev counter to the engine bay where do I connect it?
Thanks Russ
 
Unlike the earlier cars, the round dial tach is connected in series with the coil through a ballast resistor wire, so if the engine runs but the tach doesn't work the tach must be faulty.
