What This Adapter Does in the Harness
The Molex 533580250 is a 2-position in-line adapter from the Mi II 53358 series, designed to join two plug male pin ends on a 0.079" (2.00mm) pitch. Unlike a standard header that terminates to a board, this free-hanging (in-line) part lets you extend or bridge cable assemblies without a PCB — useful for daisy-chaining power or signal lines inside a harness where a board-mounted connector won't fit. The single-row layout keeps the adapter narrow, so it routes cleanly through tight cable bundles or conduit.
At 0.079" (2.00mm) pitch and 2 positions, this adapter matches the standard 2.00mm-pitch cable connectors used across the Mi II family.
Plug-to-Plug — What It Mates With
Both ends of this adapter are Plug, Male Pins, so it accepts two female receptacle housings from the same Mi II 53358 series. There's no gender change — it's a straight-through bridge. In a harness build, you'd terminate two cable assemblies with the matching receptacle (typically the 53358-series female housing) and plug each into either end of the 533580250. No board, no solder — just a crimp-and-plug splice point.
