There's loads of 3PDT true-bypass wiring diagrams online. Each of the wires going to the switch will either go to a jack, ground, the PCB, or the LED. Once you take a look at a diagram (baring in mind there's more than one way to wire a 3PDT), and compare that to what you've got, you should hopefully have a better understanding of what you need to do
Oh and Ryan at Fuzzrocious is super nice and helpful, if you want a wiring diagram of exactly what he's done, just ask
