Hello Martin,
The self-configured contact should be an AMP JPS junior timer (at least that's what it's called in our SAP system). You should find it connected to the thicker cable. We also use it when we want to transfer larger amounts.
Therefore, I would have also used this contact for procurement.
The other contact is likely to be located very deep inside, as the retaining tabs are positioned far forward.
If the contact

fits 'nicely' into the housing, I would, like Matthias

, now say:
You did it right.
Best regards, Jochen.

Damn. Phone, now Martin was faster..
