The **Harley-Davidson 72301-49A Big Twin Wire Terminal Plate** is a critical component for restoring or maintaining the electrical system in **FLH (Electra Glide) models from 1958 to 1969**. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of purchasing a 72301-49A Terminal Plate**

1. **Authentic Fit and Functionality**

The terminal plate is an **OEM (Original Equipment Manufacturer) part**, meaning it was designed specifically for the **1958 1969 FLH Big Twin** electrical system. This ensures proper alignment with the wiring harness, connectors, and voltage requirements of the motorcycle. Aftermarket or generic replacements may not match the exact specifications, leading to compatibility issues or poor electrical connections.

2. **Reliability and Durability**

Harley-Davidson parts, even vintage ones, are built to withstand the demands of motorcycle use. The **wire terminal plate** is typically made of **brass or copper alloy**, materials known for their conductivity and resistance to corrosion. This reduces the risk of intermittent electrical failures, which are common in poorly made or mismatched parts.

3. **Preservation of Original Performance**

The **Big Twin engine** in these FLH models relies on a robust electrical system for ignition, lighting, and accessories. Using the correct terminal plate ensures that the **ignition coil, battery, and starter motor** receive the proper voltage and current without voltage drops or arcing. This helps maintain the motorcycle s original performance and prevents unnecessary wear on other electrical components.

4. **Easier Restoration and Maintenance**

If you are restoring a **1958 1969 FLH**, sourcing the correct terminal plate simplifies the process. It eliminates the need for **adapters, jury-rigged solutions, or aftermarket modifications** that could complicate wiring diagrams or lead to future issues. A properly installed OEM part also makes future diagnostics and repairs more straightforward.

5. **Historical Accuracy for Enthusiasts**

For collectors and purists, using **genuine Harley-Davidson parts** enhances the motorcycle s authenticity. This is particularly important for **show bikes, restoration projects, or those aiming for concours-level finishes**. The terminal plate, though small, contributes to the overall integrity of the build.

6. **Wider Availability of Supporting Parts**

Since this is an **OEM part**, you can more easily find **matching wires, connectors, and fuses** from the same era. This reduces the risk of mixing incompatible components, which can lead to electrical shorts, fires, or complete system failure.

7. **Long-Term Cost Savings**

While the upfront cost may be higher than an aftermarket alternative, the **lifespan and reliability** of an OEM terminal plate often outweigh the expense. Cheap or poorly made replacements may fail prematurely, requiring repeated replacements and labor costs.

---

### **Cons of purchasing a 72301-49A Terminal Plate**

1. **Higher Cost Compared to Aftermarket Alternatives**

Authentic Harley-Davidson parts, especially for **vintage models**, can be **significantly more expensive** than aftermarket or generic replacements. The price reflects the **limited production, age of the part, and demand from collectors**. This may be a barrier for budget-conscious buyers or those restoring multiple bikes.

2. **Potential for Counterfeit or Mismatched Parts**

Due to the **vintage nature of this part**, there is a risk of purchasing a **replica, knockoff, or incorrectly labeled item**. Some sellers may misrepresent the part as OEM when it is actually a **reproduction or aftermarket copy**, which may not fit perfectly or function as intended. Buyers must **verify the authenticity** through reputable dealers or Harley-Davidson-approved sources.

3. **Limited Availability and Lead Times**

Unlike modern Harley parts, **vintage components** may not be in stock at local dealers. Ordering from specialty suppliers or online marketplaces (eBay, Harley forums, etc.) can result in **long shipping times**, especially if the part is rare. This delay can slow down a restoration project.

4. **Potential for Corrosion or Wear in Used Parts**

If purchasing a **used or refurbished** terminal plate, there is a risk of **oxidized terminals, cracked insulation, or degraded solder points**. Even if the part is mechanically sound, **electrical corrosion** can cause intermittent connections, leading to **starting issues, erratic lighting, or ignition problems**. A thorough inspection (or testing) may be necessary before installation.

5. **Requires Proper Installation Knowledge**

While the terminal plate itself is relatively simple, **incorrect wiring or improper crimping of terminals** can lead to **poor connections, voltage drops, or even electrical fires**. Buyers must either have **mechanical/electrical experience** or be willing to **consult a professional** for installation. Cutting corners here could void warranties (if applicable) and risk damage to the motorcycle.

6. **Compatibility with Modified or Aftermarket Electrical Systems**

If the FLH has been **modified with aftermarket components** (e.g., modern ignition systems, LED lighting, or custom wiring), the **OEM terminal plate may not integrate seamlessly**. In such cases, a **custom wiring solution** or an **aftermarket terminal block** might be necessary, reducing the benefit of using the original part.

7. **Environmental and Handling Considerations**

Vintage parts, especially those stored for decades, may be **sensitive to moisture, dust, or improper handling**. If the terminal plate has been exposed to **humidity or poor storage conditions**, it may require **cleaning, polishing, or re-tinning** before installation to ensure a reliable connection.

---

### **Conclusion**

The **Harley-Davidson 72301-49A Big Twin Wire Terminal Plate** is a **highly recommended component** for restoring or maintaining a **1958 1969 FLH Electra Glide** if:

- **Authenticity and reliability** are priorities.

- The budget allows for the **higher cost** of an OEM part.

- The buyer can **source it from a trusted supplier** to avoid counterfeits.

- Proper **installation and testing** are conducted to ensure functionality.

However, if **cost is a major concern** or the motorcycle has **significant aftermarket modifications**, an **aftermarket terminal block** or **custom wiring solution** may be a more practical alternative though with potential trade-offs in reliability and historical accuracy.

---

### **Recommendation**

- **Purchase from a reputable Harley-Davidson dealer, specialty vintage parts supplier, or a trusted online marketplace** (e.g., **Harley-Davidson Parts Center, Cycle World, or eBay with verified sellers**).

- **Inspect the part upon arrival** for signs of corrosion, damage, or mismatched wiring.

- **Test the terminals** with a multimeter to ensure proper conductivity before installation.

- **Consult a Harley mechanic** if unsure about wiring or electrical connections.

- **Consider an aftermarket terminal block** (e.g., **Sparky s, Weeder, or other high-quality brands**) that is **compatible with the FLH s wiring**.

- **Document any deviations** from OEM specs in case future issues arise.

- **Prioritize quality over cost** cheap aftermarket parts can lead to **long-term problems**.

- **Study the original wiring diagram** (available in Harley-Davidson service manuals or online forums).

- **Use proper crimping tools** and **heat-shrink tubing** to secure connections.

- **Test the electrical system** after installation (check battery voltage, starter function, and lighting).

For **true enthusiasts and restorers**, the **72301-49A terminal plate is the best choice** due to its **reliability, authenticity, and long-term benefits**. For those on a tight budget or with modified bikes, a **high-quality aftermarket alternative** may suffice but with the understanding that it may not match the original performance or longevity. Always **prioritize quality over cost** when dealing with critical electrical components.
