Dummy plug
Is there a "dummy" 7 pin plug you can plug in so the truck "thinks" it has a trailer attached?

Maybe this one?

Amazon Amazon

The links in this post and the post above aren't working for me. If they aren't working for you, search Amazon with "Trailer light tester". Most of them are less than $10.

If your intention is to eliminate the auto start / stop, there are better ways to do it.

Edit: my mistake, I did not realize the OP had a superduty with 6.7

I have one of those cheap light testers too, the factory trailer brake controller in the F250 doesn't recognize a trailer as being back there with just the light tester installed (cluster still say "no trailer connected".
But with the more expensive break tester thing installed, it does.

Thanks for the update. I wasn't sure if it would work or not. Now I'm curious what it takes to make the truck think there's something there. Probably just a resistor but that's the extent of my knowledge.
