If you are using crimp connectors for the butt joint, STOP. First, you're doing twice as many crimps, so you should have twice as many crimps to fail. More importantly, the closed end crimp connector crimps the two wires twisted together, creating a secure connection. If you go to the hardware store to buy these gated connectors, you can get 12 to 20 for about $2.99. Here you can get a lifetime supply for the average 1000 man for less than $15, or less than 0.30 cents for 20. You'll be using a lot more than you think wiring cars, boats, stereos, etc. They are fast, clean and easy to use. It is good quality and this seller ships fast.
