⚠️ Safety Disclaimer:
Working on your vehicle's electrical system can be dangerous if done incorrectly. Always disconnect the battery when appropriate, follow manufacturer instructions for all tools and parts, and wear proper safety gear. I’m sharing what worked for me on my own vehicles. Perform all modifications at your own risk. If you’re unsure, consult a certified mechanic or automotive electrician.
