Coil wiring question

I have a Femsa coil on the engine. The two terminals are labelled B & D. Which one do I connect the points/condinser wire to?

I think its the D but want to make sure

Thanks

it is a long time since I saw a coil marked like this but I would think B is battery (or power) and D is distributor. There have been a lot of ways of identifying the wiring and sometimes they are unique.

Cheers, thanks
