Review: Excellent and economical - The kit included everything I needed to complete the rewiring of my tractor. The connectors were easy to use and durable. I highly recommend this to anyone needing weather proof wiring.
Review: Always works like a charm! - I work as a Mechanic at a local national chain. I bought these because my shop foreman/service manager refused to purchase some for the shop. How I use these is to slide both wires in (through the opposing holes) until they cross through the solder. I heat gun and het the ends to hold the wires in place. I then slide heat shrink over the entire connection and heat with the heat gun. You will see the center flatten out (when the solder melts). I remove the heat gun and lightly roll the center between my fingers. Perfect connections, and hella value for your money. I should've took pictures. I was fixing 30+ wires at the engine PCM connector in a 7.3 diesel.

### ⭐⭐⭐⭐⭐ Makes great solder / water resistant connections
*by D***K on January 17, 2026*

Seems to be decent enough for the application I used them for. Good for most vehicle wiring applications. Use a very light flame torch or a lighter works. It makes a solid connection. With water resistant joint. I use these type of connections. Better than crimp connection.
