MUYI 10 Kit 2 Pin Waterproof Connector for 20-14 AWG Wire Harness 2.5mm Series Automotive Electrical Plugs with Replacement Terminal Pins Sockets and Spudger

I've put these connectors BMW motorcycles and some cars. They work great, but purchase a crimper that has a pin holder to properly align the pins and crimp the wire and insulator seal at the same time. Alignment is critical for the connector to be correctly aligned when inserted into the holder. Using a typical crimper is a crap-shoot, don't do it. Use the correct crimper and your work will look factory professional if not better.Additionally, you can buy connector terminals and the blocks separately, just search for them. I have different sizes of blocks and multiple terminals sized for many wire gauges, then select what you need for the job and don't worry about having enough connector terminals. Yes, at times I need to tweak the two connectors, usually I work with the male side, in order to push them together, but once done the pins get 'seated' better and it goes together easily afterward.Keep in mind this style of connector is NOT woaterproof, just moisture-proof, so don't buy them for submerged connectors. I used these connectors to replace an older quick-disconnect that seemed to be causing running issues on an engine's ignition system. They did the job, giving a great connection. The old connectors were similar, but shorter and not moisture-proof, so I expect the new connector to last for decades.

works as expected

Make sure you have the crimper to crimp to the wire. Nice buy for a necessity in any shop.

Good product, a couple issues with installing wire, expect to waste a few inserts to get it right

These connectors do their job well; the name brand Weather Pack connector do their job really well but they generally cost about three times as much-maybe a little more than that. You need to decide if they are worth the difference.I tried both. As far as the bodies go I was hard-pressed to see the difference.The pins are a little different matter: The big difference is the material and the side profile. The true Weather Pack pins have a definite belly to allow for the insulation under the insulation crimp point where these pins do not. This kinda interferes with the crimping. They still work pretty well but it just doesn’t make for as pretty a crimp. I think this also causes the number one complaint I see in the comments—the fact that you might have to do a little straightening after the units are assembled.There seems to be a little confusion on which pins go with which bodies. YouTube is your friend! I recommend you spend a lot of time there before you attack these couplers. About half of the people on there get it wrong (You decide which half), but there is a lot of good info on there. The confusion comes from the fact that the female bodies look like they are male and versi-visi for the male, so about half of the people say the female pins to in the male bodies and male pins go in the female bodies. The people who make these name the body with the protruding tubes the female body. Call it what you will, but that’s the one that you should insert the female pin into. If you happen to get it wrong don’t worry; they will still work. I found that either pin will work in either body.They are well worth the money, but because the pins may need a little tweaking you have to be careful when you couple them up so I’ll give them a 4. If you use name-brand pins I would rate them as 5.
