Apply some heat to shrink it down and secure it in position. Next I slide on some heat shrink tubing over the join. It will take several minutes to completely dry. Dab on a little at a time, unless you like having it drip all over. Third, I coat the exposed wires with liquid electrical tape to waterproof it. This will help the solder to penetrate the inside of the join. I’ll then move the soldering iron to press against the bottom of the join. The solder will melt and start coating the join. After apply a modest amount of rosin core solder. Once it is hot, place it directly on the join between the wires. This both mechanically secures the wires together, and bundles it together with a profile just a bit bigger than the wire. Next I use a spare strand of wire to wrap the connection together. Then take the two ends and push then directly into each other – letting the strands mix across the width of the wire. This is the standard way I try to connect any two wires together.įirst, take the ends of the two wires and strip off about 1/4 of an inch. Here is some wiring I did to extend the wiring harness on a trailer. This takes longer but the result is a very strong and durable connection. However I prefer to an even better connection, which is to solder the two wires together. This will waterproof it and further secure the wire in position. Then use a heat gun (or just a lighter) to shrink the tubing around the wire. Repeat using the other wire on the other side. This will hold it in position, and secure the electric connection. Once it is fully inserted on a given side then use pliers or a crimp tool to smash the metal around the wire. You strip each wire just enough to fully seat inside the metal part of the connector. If you must go quick and easy then use a heat shrink butt connector. It is not waterproof and vibrations can shake it loose. Twisting the wires together and using a twist cap is a guaranteed fail. For example, you may need to connect wires to the “pigtail” of wires coming out of a light or other device. Occasionally you will need to connect two wires together – end to end. Similarly make sure other parts are also marine grade. Marine grade heat shrink tubing has extra adhesive inside to secure it and make the seal waterproof. The isolating plastic is higher quality – more resistant to gas and other corrosive elements.The wire is tinned – which is an anti-corrosion coating.
