Review on 🔌 DZS Elec 4Pin 1 to 3 Ways PWM Fan Splitter Cable: Efficient Black Sleeved Fan Power Extension Cable, Female to 3X Male, 27cm/10.5 inches by Jonathan Clark

It couldn't be much simpler, but it still failed. This harness should be a 3 to 1 splitter with 4 wires/pins. Female end with 4 sockets and 3 male ends with 4 pins. The product I received had the socket properly connected, but the plug had 2 of the 3 plugs with only 3 pins. And if you think that's how it should have been, the 3 pins present weren't in a row - two pins, a space, and then a third pin. Read Description: Four-pin socket for 3 four-pin plugs! I'm waiting for a replacement but it just looks like a crappy quality control issue - that's what you get from the Chinese. I hope the replacement works.
