Vigier Guitars

HI, I have been playing an Excalibur Special for a few years. I initially got it modified to add different options for the coil split. Now I am thinking to returning it to the original state.
I have looked around for the stock wiring diagram to no avail. I have seen also on the Di Marzio's website but I found it overwhelming...
Could anyone give me a hint?
Thanks in advance!

I may be wrong, but I'm pretty confident the setup is like described here (Variant HSH4)
