Brightfour 12 Pack Quick Solderless Wire Splice Connectors, 2 Way 3 Pin Automotive, Fits 20-24 AWG

Working great

I was worried about how secure they would be. They are very secure and incredibly easy to use.

Work great as long as the wire is perfectly placed. It is very hard to close otherwise.

Excellent product!

I bought the 2 wires splice and the 3 wire splice so this review applies to both. First impression is they came some of them closed and locked and others open. Took a while to figure out how to open them. Then I remembered they mention using a pocket knife (without any other instructions). I have a small Swiss Army knife that has a flat blade screwdriver in it and the blade fits nicely into the little black rectangular depression of the main (black) body of the lock, just right behind the (transparent) lock tab. By twisting the screwdriver, it forced the locking tab to release off of its latch just a little. Then go to the other side and do the same thing again. Hold the splice just right or you will close it tight again. Once both locking tabs are released, swing the top open.

Used to connect three wires from a wiring harness for one fuel injector in a 2001 Dodge Durango 5.9. I was working in a tight space, the connector was a little tricky to work with. In the end I was able to get the wires connected. The connectors are small and do not take up that much space in the area where the wires exit the wiring harness. Compared to other connectors they are a bit expensive, but well worth the extra cost.

These little connectors appeared to be what I needed for my Govee LED light installation. However, they shorted out my lights causing me a lot more issues than if I had just used a traditional wire nut. They are difficult to unclip, so you will need a small flat screwdriver to open if you wanted to save your fingernails. But, once they clamp down on the wire they do stay in place. These would probably work best to connect really, really thin wires on a really small project.

I wanted an easy way to wire-in a Bluetooth audio adapter into my car's Aux input. Dealing with a soldering iron in such cramped quarters seemed like a pain so I opted for these connectors. I am very pleased with them. Very easy T connections. They are compact and the housing is clear on top so you can inspect the wire placement before you use pliers to clamp them down. They lock securely into place, but they can be opened and reused using a knife blade and some effort.
