Pick up a set of crimpers, and easy to use, consistent build quality, positive audible and physical click and the the connection is secure. My only recommendation would be gold connector options. Put a small amount of dielectric grease and abate corrosion. To separate will need a strong fingernail or flat head screwdriver.
I used a competitors 20-22 AWG connector on my project motorcycle because the connector was larger than 4 wires. Once the bike was finished I kept having problems with the connectors because the wires and terminals were so small, they would contact inside the connector. I replaced all of the connectors w/ these Mizu connectors and they are amazing! Easy to assemble, easy to remove terminals if you need to move a wire or forget the seal. Packaging is sooo small, perfect for a motorcycle. Automotive connectors are just too damn big. I will use these on all projects moving forward.
The connectors were just what I needed for wiring my Triumph Bonneville. Quality, size and waterproof was just whst I needed. The Honey Pot I also purchased from RevivalCycles was also used to dip solder all my connections. Real professional looking wiring upgrade wss the result of using these products. Good service and support was provided from RevivalCycles. Quality products are what I use on my upgrades
They do break, but only if subject to force it never should be. Excellent little connectors
I've pinned a lot of different connectors over the years, and these are easily the most compact weather sealed I've used. Finding drawings, exploded view, or a spec sheet wasn't the easiest thing, and the manufacturer doesn't offer much. Here's the main things: like most connectors (Deutsch, Metripack, Bosch), the female pins go in the male plug receptacle and the male pins go in the female plug receptacle. I hoped to find some drawings to provide stripping lengths and pin orientation for insertion into the receptacle body, but struck out. Ultimately they only go in one way and will click when they seat, but they're fiddly little buggers on account of the small size. I found that they would indeed take 18 gauge wire without too much difficulty, but the seal definitely was getting snug. Revival offers a great value assembling these as a kit, and their markup is quite modest compared to sourcing these yourself. I'd work with them again for sure. Note that the three pin receptacle is just a four pin receptacle with one port in the seal plugged. No dimensional difference. The small size is perfectly suited for sanitary installations on motorcycles running low amperage draw wires (e.g. Motogadget M-Unit installations).
These connector pairs were just the ticket for my Dyna's wiring. Changing out and relocating the front turn signals required cutting the factory wiring. Instead of solder splicing, these connectors were small enough to hide the union behind the headlight. Much smaller than the Deutsch ones...
Order extra terminals. It took a bit of practice to get the back of crimping.... Great connectors. Easy to use.
Even smaller and better made than I expected
These are great connectors and I've not had a single issue with them, quality-wise, though they are pretty easy to mangle if you're hamfisted with the connectors. The only real extensive issues I have with these are: First, I'd love to have a 5+ pin connector version instead of having to use the other connectors in combination. Second, as mentioned, the plastic is quite soft and the clips are easy to mangle with a small tool if you aren't careful. Third and last, if you accidentally mis-pin them or if you need to remove a pin to fix a crimp or what-have-you, they are extremely difficult to disassemble without damaging them, such that one of the two-pin connectors I ordered no longer accepts pins as the locking clip no longer can hold the metal pin in place. Other than those issues I super love all of these connectors I've used. More colors would be pretty cool too since then I could color-code them easier than using paint markers or heat shrink tubing on the wire.
