The only option is to create a dummy Cavity Seal, which is marked as "Exclude from Bill of Material" that defines the required Cavity Plug. Then for the Deutsch GT Series connectors assign this Cavity Seal.
In VeSys Harness where no wire exists it can select the appropriate Cavity Plug.
Does this answer your question ?
Oooopps sorry I meant Deutsch DT Series and not GT Series! Apologies to anyone who has scoured the Deutsch website looking for this 'new' connector range
