Hole Size Needed to Install the Fifth Wheel and Gooseneck 90 Degree Wiring Harness # 5701-003


What size hole will you have to drill in the side of the bed?

Expert Reply:

You will need to use a 2 inch hole saw to install part # 54701-003 Fifth Wheel and Gooseneck 90 Degree Wiring Harness in the bed of your 2006 Ford F-250/350 SuperDuty.

I have linked you to an install video showing a similar part being installed on a 2002 F250. The procedure shown in the video will be identical to the procedure for installing the wiring harness on your truck.
