Re: A wiring diagram needed
You really can't do much fancy wiring with a standard 5 way and 2 humbuckers.
You would really need a 4 pole switch for that, but in your position, just to get it working for now, I would simply go with a three position type wiring (with no splitting), leaving 2 of the position dead (or wire it so they match the position closest to it) and then order a Super Switch from Stewmac.
I have one in my 520 and the way I have it wired I have;
Position 1: Full bridge humbucker
Position 2: Bridge side single on the bridge, and neck side single on the neck.
Position 3: neck side single on neck
Position 4: Both inside single coils
Position 5: Full neck humbucker
I don't remember how I wired it, but it wouldn't be difficult to find something similar.
