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.
