It carries a blue housing, a latch holder for vibration-resistant mating, and a free-hanging (in-line) mount style.
What the Sealed Housing and Latch Mean for the Build
The sealed feature means this housing, when mated with the correct seal-capable header and properly crimped terminals, keeps water and dust out of the contact interface — critical for a harness that runs along a frame rail or inside a wet engine bay. The latch holder locks the pair together so vibration from a running engine or a piece of industrial machinery won't shake the connection loose.
