Neff spark generator—- cant understand instructions

Is it me or, are all the BSH 😕 sparepart instructions that come with the bits written for the benefit of the writer and not for the guys fitting the bits.

Trying to fit new generator to Neff T2764N0/01 using Prt no 604406 which is a replacement for original that has a third terminal

Anyone had to do one of these and knows how to do it I would appreciate their advice

Thanks,

Mike
