Critical Safety Precautions
Before starting any wiring work:
- DISCONNECT NEGATIVE BATTERY TERMINAL: Prevents shorts and electrical damage.
- VERIFY DIAGRAMS: Cross-reference colors and functions using multimeter testing (power, ground, continuity). Factory diagrams are most accurate.
- Beware Airbag Wires: Yellow connectors often indicate SRS (Airbag) components. DO NOT probe or cut these wires.
- Use Proper Tools: Employ solder and heat shrink or quality crimp connectors, not electrical tape alone.
Finding a reliable diagram involves checking official channels, established automotive communities, and specialized databases. Always test wires with a multimeter before making connections.
