Specs At A Glance

Good To Know

Q: Is this harness a plug-and-play replacement for a Ford van? A: Yes, the harness uses factory-style connectors and follows the original routing path, so it plugs directly into the engine sensors, injectors, and ECU on 2006-2007 E-Series diesel vans without wire tapping.

Q: Will this harness fit both the 6.0L and 6.8L engines? A: This harness is intended for the diesel engine; confirm the engine type and VIN before ordering, as gasoline engine wiring differs.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
