But most automotive wiring uses 12- or 14-ga.

Best way to solder automotive wires. This helps to spread out the heat when the tip touches the wires. The most reliable way of joining two wires together is by soldering. The other safe connection option is the crimp connector being simple and easy to use they are popular however dont always offer the longevity of soldering.

The broken wires can be repaired without replacing the entire harness or section. Do not over tin the wire or solder may flow up under the wires insulation causing it become rigid or you will end up with globs of solder on the terminal that will have to be removed. The wires can then be situated together by further twisting them blending them end to end or wrapping one around the other for a splice.

There is one way to twist wires together for soldering- a horizontal twist that yields a continues length of wire. Best Automotive Pin Wire Connectors. Apply solder to the top until molten solder.

Agreed the way to stop wires falling off is to avoid flex anywhere near the soldering point. Rosin flux is a compound that helps clean the wires and allows the solder to stick to them. Other wires I just crimp and cover with heat shrink if possible.
