I'm watching this with great interest as I'll be coming up to the same issue - my particular cover panel and 3-way switch aren't covered in the PBG tutorials and I've had to scour the interwebs (without much luck) for information on wiring this type of "import" switch. And I'm going to have the added fun of doing the tone riders as well.

I'm inclined to get a proper telecaster three way switch, given that I can get a genuine Fender one from a reputable dealer for just under AUD$30.
