How do know the wire harness is OK? Has it been changed?

I can almost outrule the wiring harness.. first visual inspection does not show any cables which are brittle...

second.. I measured all the cables going too and coming from the sensors for shorts and high resistance.. No

third ... I recorded the signals from the plug which goes directly into the ECU (that means including the cables.. ) The oscilloscope trace is attached to the original post..

There must be something wrong in the way the signals look. I suspect the relation of the cam signal and the crank shaft signal.. what is the correct timing? (phase)
