It will be helpful for me to understand this for the future because I'll probably build a seven string at some stage

Sorry, I missed this in my last reply.

Yes, you are correct. You just need one extra link wire on each side, to connect the red and green coloured terminals in the top-middle diagram to the output wire that heads off to the pots.

If you have some alligator clip test leads (or can hack something up with paperclips and wire) you can temporarily bridge the connections without soldering to make sure you have the right terminals identified. The DiMarzio diagram has the lug ordering reversed from the Fralin one, so I think one is looking from the top of the switch and one from the bottom. I tried to account for this, but testing with temporary connections is the safest approach.
