CAUTION:
- Soldering for a long period of time could affect the surrounding electrical circuit. Apply soldering for an extremely short period of time.
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 until the plastic melts on both ends.

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 due to excessive heat.
