I think the previous owner wired this switch into the trailer brake. I think that blue wire specifically controls the trailer brake. Why on earth would someone want to turn off their trailer brake and only use the tow vehicle brake?
I haven’t used the expy to tow my RV yet (I’ve only owned it for the Expy for a week). I did hook up the RV’s 7-pin cable and tested everything. It all works and the switch has no effect. But... I didn’t test the trailer brakes since I didn’t move the trailer. I’ll test that next weekend.

Your entry way in, is in the drivers side of the truck. Behind the panel, with a Mirror. The code is there. Open the panel to look. The button is for the rear window defrost.

I think the button showes a rear defrost emblem on it? Ask MOM?

The code is always on the ECM unit to a ford truck

The small, round switch. It's just on/off. No image.

maybe they had some type of accessory that plugged into the trailer plug and it would trigger the vehicle to think it was towing while he wasn't giving him a need to disable it? its a guess...

I think before I trade in ours I will do something similar.
