352Pcs Waterproof Car Electrical Connector Terminals Automotive Electrical Wire Connector Plug Kit 1/2/3/4 Pin Connectors Male and Female

Works great! Water resistant! Used it to rewire my motorcycle, works great so far

Used to wire up some fog lights. Nice to be able to get a cleaner install. Working with thicker gauge wire isn't the easiest but that's my problem. There is a world of difference compared to some of the connectors on cheap harnesses I have received with things in the past

There is definitely a learning curve to these connectors and the instructions, while sufficient, do not prepare you for the frustration. My two top tips below.Make sure that the exposed wire does not go too deep into the female/male prong as that can prevent the prong from locking into the plastic connector housing.Use a pair of needle nose pliers to crimp these rather than actual crimpers. It takes a little finesse but works much better in ensuring that the both wings properly fold over the wire and waterproofing rubber piece.

Simple to use and worked great for my tail light connections.

Just as described, can't wait to try them out.

There are several connectors included, from single pin to 4 pin. My experience so far with the THREE pin connectors has been bad. The middle connector (slot 2) on ALL of the three pin female side connectors WILL NOT fully engage to hold the pin. I went through 6 or 7 of the metal pins trying to get one in the middle slot, decided to try every 3 pin female, and NONE of them fully seat or lick in the middle hole.

Great

I find this a very cost effective way to establish non critical connections. I cannot attest to its water proof nature or if it really can handle ten amps of current across those small contacts. However I believe it to be a cost effective solution for many applications. There are no directions that come with this kit. It is pretty intuitive with the possible exception of the little red inserts. I questioned the vendor and he sent me some guidance that was pretty good. Once I realized that the red insert went into the connector half that did not already have one, it was pretty strait forward from there. It struggles to accommodate large diameter wires (18 Ga with what I would consider standard insulation) as it becomes difficult to get the water seal properly retained and crimped. Proper orientation of the locking tangs was another question. However you can look down the barrel of the connector and see the retaining lock so that is not an issue. Just line the retaining tangs up with the retaining locks and you are all set.All of these things are relatively minor however the fact that you cannot remove the pin once it is locked in may be an issue for some.I was all set to use my razzle dazzle ratchet crimpers on these connections when I discovered that even though they had a "B" crimp die set, the jaws were too wide. A standard "B" crimp tool works great but you may need to crimp it twice to get it tight.One added plus - I grabbed a sensor cable from a 2006 Chevrolet because it looked like a direct fit. After mating it to one of these connectors I was able to measure continuity through the pair.
