7 way trailer plug issue...
I have an '09 Ford F450, and I've got an 'ongoing' trailer brake issue. I've taken the truck to my local Ford dealer ($100.00+ to check) and said they could find no problem, but if it still doesn't ...

Thanks Scott! Yes, the folks at the trailer repair shop used their own device to send power, and apparently all is fine on the trailer. I'm hoping it's not the controller (I believe it's synced to the trucks ECM) which makes it then having to be set up at the dealer, making things more expensive. Hoping if a change to the 7 pin harness is done, it will find a problem. I did notice a lot of dust/dirt inside near the pins when I opened the harness door. I did a trip where there was a fair bit of mud and gravel, so between that and the wet conditions here in the northwest, anythings possible.
