Standard Ignition GPH106 right diesel glow plug wiring harness for the 2003-2004 Ford Excursion V8 6.0L and other vehicles connects the passenger-side glow plugs to the vehicle's electrical system. The harness carries current to the plugs that warm the engine for cold starts.
Hard starting in cold weather or a glow plug warning light can come from several parts besides this harness. Before you replace it, rule out the glow plugs themselves, the control module or relay that powers them and the battery supply; a shop can test the electrical side.
This glow plug wiring harness is a direct OEM replacement for the 2003-2004 Ford F-250 Super Duty V8 6.0L and the 2003-2004 Ford F-350 Super Duty V8 6.0L. This listing is one harness for the right side, and that side takes one; the left side is a separate part. If your vehicle is not named here, look it up in the "Vehicles it fits" section of this page.
