20Pairs JST XH 2.54mm 3Pins Connector, 2.54mm Pitch Female and Male JST Connection Plug Header Expansion Wire with 200mm 26AWG Cable

Works as intended just pay attention to polarity they may be different the what your current setup is.

Bought these to match the JST plugs of the LEDs on my Roomettes model train structure interiors. They do match, but watch the polarities. The first one I tried (to make sure it fit) had the red and black wires reversed. Not a big deal on LEDs, just reverse the connection, but in other applications could be trouble. You get 20 each male and female connectors with about 7.6" of wire stripped back about 1/8" on the ends. Would rate at 5 stars if not for the polarity issues; haven't tested how many are reversed since this is a very basic error which shouldn't happen. I think these will also fit Woodland Scenics Just Plug system, but haven't verified.

These were complete. I had some with the wires kinda out of the connector but I won't go into detail 😁. These are SOLID THOUGH! They're worth spending your money on.

I build amplifiers and other electronic projects, often using prototype "perf" board. Its always difficult to get the connections between boards to look tidy. These are excellent for this purposes. My only complaint is that the leads are too short for some applications.

They are functional and fit the male or female connectors, but the pictures make them appear to be pre-assembled with a male on one end and a female on the other. They separate pieces with half being male the other half being female. Yes, some soldering and you're in business, but I was wanting pre-assembled. Just be aware the pictures aren't representative of what you'll receive.
