Doepfer

I am getting some schaffer panels made to modify my doepfer modules 
to larger knobs and 1/4" jacks.
On the doepfer pcb's there are 4 holes where the onboard jacks fit.
If I am wiring these into Switchcraft jacks, which pins do I connect 
to where. Sorry if this is a muppet question but I am really stuck.
Thanks in advance
