Which 4-Way Wiring Harness Fits My 2004 Ford Expedition

Question:

product #C55384. Checking to see if this is the harness that is installed into the vehicles wiring to provide a 4 plug at the rear. I purchased a 2004 Ford Expedition used and not sure if what is there, which is now faulty, was factory or something added by previous vehicle owner.

The Curt T-Connector Wiring Harness # C55384 is what provides your 2004 Ford Expedition with a 4-way connector by plugging directly into the 7-way harness that is included with the factory tow package.

If you only have a 4-way that is hard wired into the Expedition then I recommend cutting off the existing defective plug and hardwiring a new one with the Curt Wiring Harness # C58044.
