Average Cost to Replace Wiring Harness
Wiring harness replacement costs depend on harness complexity, labor time, and component sourcing. Complex harnesses in electric, luxury, or high-end vehicles increase the replacement price.
Cost Breakdown: Parts vs. Labor
Wiring harness replacement includes two main cost elements: parts and labor. Parts make up 40–60% of the total charge. For example, a main engine harness for a Toyota Corolla averages $350–$650, while a high-end European sedan harness approaches $2,000. Labor charges account for 40–60% of the expense, based on shop rates and install time. Technicians often need 4–10 hours for full removal and rewiring. In Florida, labor rates for replacement at independent shops usually range from $75–$150 per hour. Cloom Tech offers custom harness assemblies manufactured in Florida, helping local businesses minimize logistics and expedite repair timelines.
OEM vs. Aftermarket Harness Costs
OEM wiring harnesses cost more than aftermarket options due to manufacturer-specific materials, connectors, and certifications. For instance, an OEM harness for a BMW M3 may cost $1,800–$2,200. Aftermarket harnesses for the same application typically fall between $400–$900, though compatibility may vary. OEM harnesses guarantee fit and performance, suitable for warranty or precision-critical applications. Aftermarket harnesses suit older vehicles or cost-sensitive projects. Cloom Tech engineers produce custom harnesses to OEM spec or custom design in their Florida facility, offering validated alternatives for manufacturers, fleet operators, and repair centers seeking both quality and value.
Ways to Save Money on Wiring Harness Replacement
Reducing wiring harness replacement costs often involves reviewing the replacement process and parts sourcing. Strategic choices in service and part selection let car owners control expenses without sacrificing reliability.
