Plug on pressure selector NG

Moinsen, I once again spent my day reading in this forum. And again and again I came across the printer. What he does, what he does, understood everything. Only one thing surprised me. Here is always spoken of a plug. So I’m again to my car, the hood opened and see, no plug. Searched in the hood, no free plug found. So already a few, but none of them would fit. Is it right that the printer over on d This is because I have a connector for a plug, but unfortunately not a suitable plug… Am I on the right track or am I on the absolutely wrong component??? It’s the NG 133 HP, by the way.
