How To Solder Car Wires Together

When wound tight you should fold the twisted copper piece flat to one wire and cover with insulation tape.

How to solder car wires together. The most secure and durable way to splice two wires together is to solder them. When your soldering iron is all prepped and ready to go its time to solder the wires. Soldering two wires together requires a soldering iron and solder.

Crossing the Streams. In the case of stranded wire always keep the individual strands together after stripping the insulation by firmly twisting them together or better still applying a little solder. The process for soldering 3 wires together is the same as splicing 2 4 or even 10 of them.

Be sure theres enough consistent solder left on the tip. Use nothing but 60-40 rosin-core solder intended for electrical wiring. Slide the existing wire into the open side of the connector then put the end of the wire you wish to connect to it into the other side.

Repeat this process on the other wire. I will be using a power probe butane soldering gun. For this example we solder the same two 18 AWG wires together end to end.

Once coated sufficiently move the shrink tube and heat it so it makes a snug fit around the wire. Twist the two wires together by wrapping them around each other in a clockwise fashion. The process of soldering is taking two or more wires and joining them together and then using heat to melt electrical solder connecting those two wires permanently.

I will be using a power probe butane soldering gun. This tool worked the best for me in the automotive application and make it a breeze get that tuff to reach wires repaired soldered and sealed properly. Remember to put the heat-shrink tube over the wire before soldering then move it into place.
