Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Wiring

Tools Required: Screwdrivers, wire connectors, multimeter.
