Installation Tips
After purchasing my harness, I learned a few installation tips that made the process easier:
- Disconnect the Battery: Safety first! I made sure to disconnect the negative terminal of the battery to avoid any electrical issues.
- Use a Wiring Diagram: If you’re unsure about the connections, consulting a wiring diagram can be incredibly helpful. I found a few online that clarified the wire functions.
- Test Before Finalizing: Once I made the connections, I tested the radio before reassembling everything. This step saved me from having to redo the installation if something wasn’t working correctly.
Recommended Brands
Through my research and purchase experiences, I came across several reputable brands that consistently received positive reviews:
- Metra: Known for their high-quality products, Metra offers a harness that fits perfectly with my Firebird and includes easy-to-follow instructions.
- Scosche: I found Scosche’s wiring kits to be durable and reliable, making installation a breeze.
- Pioneer: While primarily known for their radios, Pioneer also provides wiring harnesses that seamlessly integrate with their systems.
Where to Buy
I found that several online retailers had competitive prices for these wiring kits. Websites like Amazon, eBay, and specialized car audio retailers often have good deals. I also checked local auto parts stores, as they sometimes carry these kits and can offer immediate availability.
Conclusion
Choosing the right aftermarket radio harness wiring kit for my 1989 Pontiac Firebird was a vital step in upgrading my audio system.
