Hello Michael,
Thanks for writing in!
It looks like you already found the best option. The Curt 5th Wheel/Gooseneck Custom Wiring Harness with 7-Pole Connector - 7' Long # C56070 is a great fit for your 2004 Ford F-350 Super Duty.
Installation is straightforward since it plugs into the factory 7-way wiring at the rear of the truck. From there, you'll route the harness up to the bed and mount the new 7-way where it's most convenient for your setup. There is some drilling required to mount the connector, but there is no cutting or splicing into your factory wiring. I attached an image of the completed project.
What are you planning to tow that has you adding the 7-way in the bed? Something fun like a 5th wheel?
