Trailer brake controller

I have an 05 F-250 that i added the factory trailer brake controller to, replaced master cylinder and enabled the controller with forscan. EVERY time i hit the brake "check trailer' pops up on the dash. I haven't even hooked up a trailer to it yet since adding the TBC... bled brakes, checked fuses for anything pertaining to TBC or trailer, cleaned connections and used anti-ox on 7 pin connector and connector on back of 7 pin connector... don't know what to try next, any ideas? It is a Dorman TBC, brand new from rock auto

maybe backup to the trailer so that you can plug it in and then hit the brakes and see if the message still pops up/clears.

It does it when i press the brake pedal, not the manual brake on the controller. It even shows the trailer being red and not connected but still says to "check trailer" on the dash
