What is involved in converting an original Defender cabinet to the Multi-Williams? I have the Multi-Williams jamma pcb and was wondering if it was a simple board swap
 
If it is a Jrok Multi then you need to make an adapter harness since James no longer sells them.
It connects the Jrok to the original boards.
Here is a link to a wiring diagram to help you out. Page 6 has harness adapter info.

The other option is to just use the Jrok with a jamma harness and switcher instead of the originals.

Also have a look at two example wiring diagrams.
