What is an engine wiring harness?

Your Mercedes engine is precision-engineered to deliver reliable control and unparalleled power for its class. To do this, it depends on a sophisticated electrical network to control various primary functions. Your Mercedes 400E engine wiring harness is designed to carry these signals. Physically, your harness is a bundled set of insulated wires fitted with appropriate hardware and connectors. It attaches at multiple points along your engine and electrical system.

How much is a new wiring harness?

Wiring harnesses for the 400E tend to cost somewhere between $450-510. These parts must be rigorously tested for safety, as they carry high voltage currents through the punishingly hot conditions of your engine compartment. Make sure that you're getting a quality harness to avoid premature deterioration, loss of electrical signal and fire risk.

What are the signs that a harness needs replacement?

Nearly every engine function that requires electricity could be affected by a failing Mercedes 400E engine wiring harness. That includes maximum performance, fuel efficiency, idling and acceleration. If you're having trouble diagnosing any of these problems, check your harness. Look for signs of:

  • Corrosion or buildup on the contacts
  • Loose connections
  • Brittle or chalky insulation
  • Exposed wiring
  • Damaged insulation or housing
  • Improper repair, such as taping
