Question:

There is a plug under the bumper currently. We both know that is terrible for a gooseneck. I want to drill and mount a new plug in the bed and hopefully have it plug directly into factory wiring. I just bought this truck last week so it's new to me. Like I said my trailers have the old style metal housing 7 pin round plug.

It sounds like your 2005 Ford Super Duty was outfitted with the 7-way blade system which is the most common in the market today.

To adapt your 7-way blade to a 7-pole round for your trailer, I recommend the Pollack # PK12728. This 7-pole connector is prewired to simply plug into your truck's 7-way plug. It has the # PK11720 connector you referenced but is pre-wired like you are desiring.

A great mounting bracket for the # PK12728 is the # PK11771.

Thanks for clarifying what your setup looks like currently on your 2005 Ford Super Duty, it helped me understand what you will need for your gooseneck setup. First, I recommend the Bargman gooseneck 9 foot long 90-degree wiring # 50-97-410. Then you will need to adapt the 7-way blade for your 7-pin round connector on your gooseneck. You can do this with the # PK12728 mentioned before. The 7-way connection can be secured with a zip-tie and electrical tape to keep out debris and stored under the vehicle so that you can mount the 7-pole connector to the bed wall instead. At this time there is not a prewired 7-way to 7-pole round gooseneck bumper to bed adapter, the above mentioned products will be the easiest pre-wired route for your 2005 Ford Super Duty and gooseneck trailer. I have included a video of the Bargman being installed for you to reference when mounting your 7-pole round connector.
