I have a 74 2.0 with the blue bosch coil

I wanna test my coil.
What are the ohm numbers I need to see between which points?
Wich wire is ground?
Is the other getting 12V?

Side question:

The only real test is to bolt on a new one and see if the problem goes away. You should have close to zero ohms between the LT connections (1, 15 or +,-). Most coil problems arise when they are hot and aren't a dead short. So testing with an ohm meter isn't helpful.

The only true test is to use a scope on the engine while it's running and analyze the feedback, which takes expensive equipment and extensive knowledge.
