Review HARLEY DAVIDSON Nos Headlamp Wiring Connector Socket Harness fits FXR FXRT FXWG

The **Harley-Davidson 70077-80 NOS (New Old Stock) Headlamp Wiring Connector Socket Harness** is a meticulously crafted, high-quality replacement component designed to restore or upgrade the electrical connectivity of the front headlamp assembly on select Harley-Davidson models, including the **FXR, FXRT, and FXWG** series. This genuine OEM (Original Equipment Manufacturer) part ensures seamless integration with the bike s existing wiring system, maintaining the integrity of the electrical circuit while delivering reliable performance. Crafted from durable, corrosion-resistant materials, the harness features a robust **socket connector** that securely interfaces with the headlamp s wiring, preventing loose connections that could lead to intermittent power loss or electrical malfunctions. The **NOS designation** signifies that this part has been sourced from Harley-Davidson s inventory of pre-owned, high-quality components, often pulled from returned or surplus stock, ensuring it meets the same rigorous standards as new production parts. The design includes a **flexible yet sturdy wiring loom**, engineered to withstand the vibrations and environmental stresses of motorcycle operation, while the **precision-molded connectors** guarantee a tight, corrosion-free fit. Whether replacing a worn-out or damaged original harness or upgrading an aftermarket headlamp installation, this part is an essential component for maintaining optimal lighting performance and electrical reliability. Its compatibility with classic and modern Harley-Davidson models makes it a trusted choice for both restoration projects and routine maintenance, ensuring that riders can trust their headlamp to illuminate the road ahead with clarity and consistency.

### **Pros and Cons of buying a Harley-Davidson 70077-80 NOS FXR/FXRT/FXWG Headlamp Wiring Connector Socket Harness**

#### **Pros:**

1. **Original Equipment Quality (OEM)** Being a **New Old Stock (NOS)** part, it is manufactured to Harley-Davidson s original specifications, ensuring compatibility and reliability. Unlike aftermarket parts, it is less likely to cause electrical issues or fit problems.

2. **Reliability and Durability** Harley-Davidson parts are known for their robust construction, and this wiring harness is designed to withstand the demands of motorcycle use, including vibration, heat, and moisture resistance.

3. **Exact Fitment** Since it is a genuine OEM part, it should fit perfectly on **FXR, FXRT, and FXWG models** without modifications. This reduces the risk of improper connections that could lead to electrical shorts or malfunctions.

4. **Long-Term Performance** Using an authentic part minimizes the risk of premature failure, which can be costly and inconvenient, especially on a motorcycle where electrical issues can affect critical systems like lighting and instrumentation.

5. **Resale Value** If you plan to sell your bike in the future, having original or NOS parts can make it more appealing to buyers who prefer authenticity.

6. **Warranty Coverage** Harley-Davidson parts often come with manufacturer warranties, providing peace of mind in case of defects.

7. **Compatibility with Other OEM Components** Since it is an original part, it is more likely to work seamlessly with other genuine Harley-Davidson wiring, connectors, and harnesses.

#### **Cons:**

1. **Cost** NOS parts are typically more expensive than aftermarket alternatives. The price may be significantly higher than a used or refurbished version, making it a less budget-friendly option.

2. **Limited Availability** NOS inventory can be scarce, especially for older model years. You may need to wait for restocking or source it from a specialized dealer, which could delay repairs or upgrades.

3. **Potential Overkill for Minor Repairs** If the wiring harness is only slightly damaged or if you re replacing it as a precaution, an aftermarket or used part might suffice without the premium cost of NOS.

4. **No Significant Performance Upgrade** This is a functional replacement part, not an upgrade. It does not improve power, handling, or aesthetics only reliability and authenticity.

5. **Storage and Handling Risks** NOS parts are often stored in warehouses for extended periods, which could expose them to environmental factors (dust, moisture, or temperature fluctuations) before purchase. Inspecting the part upon arrival is crucial to ensure it is in pristine condition.

6. **Dealer Markup** Purchasing from an authorized Harley-Davidson dealer may come with additional fees or markups compared to buying from a private seller or online marketplace.

7. **Not Necessarily "New"** While labeled as "New Old Stock," the part may have been sitting in inventory for years. It is not a brand-new production item, which could be a concern for those seeking the latest manufacturing standards.

### **Conclusion:**

The **Harley-Davidson 70077-80 NOS FXR/FXRT/FXWG headlamp wiring connector socket harness** is an excellent choice if you prioritize **authenticity, reliability, and long-term performance**. It is ideal for restorers, enthusiasts who value OEM parts, or those who want to ensure their bike retains its original integrity. However, if budget is a concern or the part is only needed for a minor repair, an aftermarket or used alternative may be a more practical option.

For most serious riders who demand **confidence in their bike s electrical systems**, the investment in a NOS part is justified. It reduces the risk of compatibility issues, ensures proper function, and aligns with Harley-Davidson s engineering standards.

### **Recommendation:** - **Buy the NOS part if:**

- You are restoring or maintaining a classic Harley-Davidson.

- You want to avoid potential electrical issues from non-OEM components.

- You are willing to pay a premium for guaranteed fitment and reliability.

- You plan to keep the bike long-term and value original parts.

- **Consider an aftermarket or used alternative if:**

- You are on a tight budget and the part is only needed for a basic replacement.

- You cannot find the NOS part quickly and need a solution sooner.

- You are comfortable with aftermarket brands that offer similar quality at a lower cost.

Ultimately, weigh the importance of authenticity against your budget and urgency. For most riders who take pride in their Harley, the NOS part is the best choice for peace of mind.
