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

Perfect for a wiring project, like my wiring of a standalone wiring harness

Great item

Time will tell how these hold up. Instructions are simple and they seem like they'll hold up.

Good kit for multiple wiring situations. I ripped off a 4 wire fitting from my dirt bike in a crash. Easy to put it back together with this kit and it seems comparable to the OEM fitting.

I used this connector kit to replace all my bad connectors on my 1988 Suzuki Samurai. Used a crimping tool that you can get with or without the kit. These connectors are easy to put together. They unplug and plug back together very easily. I would recommend these for any water tight connection's. AAA+

The connectors were not too sturdy for my usage. Two sets simply didn't stay together. For my piece of mind, I used another product.

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.
