Better still use proper straight through connectors. The professional type, they have solder inside to join the wires, once heated the solder melts and joins the 2 wires, then the outer casing shrinks to fit and also releases glue which seals the joint water tight. that way you'll not get any more problems. the only problems caused by soldering is if you dont support the wires and they vibrate, the solder will crack and you know where that will leave you
Vehicle wiring products sell them..........
