Dependable heat shrink connectors.
These are decent connectors. Probably the pick of the Chinese bunch. I find them as good as all the Ancor stuff I have used.

Fast and easy to use; best connector for outdoor exposure.
Not much to say on these connectors, they are easy to use and almost idiot proof. They are quick to use and are weather proof for exposure to the elements. A heat gun works and is preferred, I don't recommend open flame but I suppose it would work if you are super careful. It is listed for 16-22 gauge wire but it looks too big for two 22 G wires. There are other sizes and I recommend you try to stay in the center of the range if possible.

Love these connectors, the glue inside makes them a great waterproof, solid connection, especially for vehicles. No issues at all, they work well!

A good and economical bulk pack of wire butt connectors for most automotive needs. Provides a solid crimp connection and the heat shrink capability further secures the connection and makes it waterproof. Note that this connector is crimp only and does not include solder to make the connection.
