If your car’s wiring harness needs to be repaired or replaced, you might be worried about the cost. The wiring harness is a crucial component that carries electrical signals and power throughout your vehicle, and damage to it can cause a range of issues, from malfunctioning electronics to complete system failures. In this article, we’ll explore the typical costs associated with repairing or replacing a car wiring harness, as well as factors that can affect the price.
Average Cost of Wiring Harness Repair
The average cost to repair a car wiring harness ranges from $1,300 to $1,700, with the labor cost typically between $400 and $500. However, the total cost can vary depending on several factors, such as the make and model of your vehicle, the extent of the damage, and the complexity of the repair.
For example, a study by CarAdvise found that the national average cost for an engine wiring harness replacement in 2024 is between $338 and $5,516, with an average of $607. This wide range reflects the differences in parts and labor costs for various vehicle makes and models.
In some cases, the cost of repairing a wiring harness can be quite high. One Acura TLX owner reported a repair estimate of almost $3,000, which included $2,499 to replace the wiring harness and an additional $270 to drain and recharge the air conditioning system. The high cost was due to the extensive damage caused by an animal chewing on the wires.
Factors Affecting Wiring Harness Repair Cost
Several factors can influence the cost of repairing a car wiring harness:
Vehicle make and model: Luxury and high-performance vehicles tend to have more complex wiring systems, which can increase the cost of repairs.
Extent of damage: If only a small section of the wiring harness is damaged, a repair may be possible at a lower cost. However, if the entire harness needs to be replaced, the cost will be higher.
Labor costs: The labor cost can vary depending on your location and the hourly rate charged by the repair shop.
Parts availability: If the specific wiring harness for your vehicle is not readily available, the cost may increase due to the need for special ordering or custom fabrication.

Preventing Wiring Harness Damage
To avoid the high cost of wiring harness repair, it’s essential to take steps to prevent damage in the first place. Some preventive measures include:
Regular inspections: Have your vehicle’s wiring harness inspected during routine maintenance to identify any signs of wear or damage.
Protecting against rodents: Rodents can chew through wires, causing significant damage. Use deterrents like ultrasonic repellents or seal any entry points to prevent them from accessing your vehicle’s wiring.
Avoiding harsh chemicals: Some cleaning products and chemicals can damage the insulation on wires, leading to short circuits. Use only approved cleaners and avoid spraying water or other liquids directly on the wiring harness.

When to Replace vs. Repair
Deciding whether to repair or replace a damaged wiring harness depends on several factors, including the extent of the damage, the age and mileage of your vehicle, and your budget.
If the damage is limited to a small section of the harness and the repair is relatively straightforward, it may be more cost-effective to repair it. However, if the damage is extensive or the harness is difficult to access, replacement may be the better option.
If your vehicle is older or has high mileage, the cost of repairing the wiring harness may not be worth it, especially if other components are also showing signs of wear. In such cases, it may be more practical to consider replacing the vehicle altogether.
Ultimately, the decision to repair or replace a wiring harness should be made in consultation with a qualified automotive technician who can assess the extent of the damage and provide a recommendation based on your specific situation and budget.
