DIY Thrustmaster wheel help

[_KRT20_]

Hi everyone, I am currently planning a DIY wheel rim for the Thrustmaster T300. I am currently trying to find a good way to assign around 12 buttons on the wheel. Along with this, I have below pictured the connector that all Thrustmaster wheels have on them (the 6-pin din black connector) and ideally, I would like to be able to plug the white end into whatever circuit board I may use, as I don't really want to program.
Thanks everyone
