There's only one pin on the bottom that you really need be concerned 
about - that's the other end of HV winding.  It generally sits out on 
its own a bit.  Check between the HV output stud and the various pins 
with a resistance tester until you find the right one.

All the F/B plans that I have seen use a DIY primary - don't panic 
because this is often only about ten turns!

The last one that I made (555 driving power MOSFET) was about half a 
dozen turns of insulated hookup wire on the other 'leg'.

You'll find all the schematics, instructions, etc., that you want from 
this Google search:

Hope this helps.

Cheers
