Prs se 24 floyd out of phase

[SierraHotel]

Hi, I bought the guitar new at a really big store in Germany. The wiring was messed up right away. So I returned it and the technician and he tried to fix it. Now the Neck and Bridge PUs sound right and the coil split works fine. But it definitely sounds out of phase in the middle position. I cannot find the wiring scheme for this guitar. How can I fix it?

I would like to fix it myself. Don't trust the techs of the store anymore

Thanks in advance!
