Repair-Use Connector Replacement Procedure: Soldering

  1. Twist together firmly the cores of the wiring harnesses being connected and apply soldering in that area.
    CAUTION:
    • Soldering for a long period of time could affect the surrounding electrical circuit. Apply soldering for an extremely short period of time.

  2. Cut the ends off the connected area, and apply the soldering iron tip to the wiring harness after removing any fraying.
  3. Set the heat shrinkable tubing to the soldered area and shrink the heat shrinkable tubing at a temperature of approx. 100 °C {212 °F}  using a drier.
    CAUTION:
    • Completely shrink the heat shrinkable tubing to the wiring harness leaving no gaps.
    • Perform the work being careful not to melt the insulation of the wiring harness by excessive heat.
