No, I have even put some connector grease in the main plug. I think I am going to have to either change out the whole trailer plug or go through and check all connections in the system. It would not be that bad but, it does the seatbelt chime when the message comes up.

Mine did that a few times when I first bought it. The previous owner had a trailer plug put into the bed for a fifth wheel. I had to completely rewire where they spliced into the factory harness. They just used crimp connectors and a little bit of electrical tape.

I think there is a TSB about that on these trucks. Ford found that the design allowed moisture in but then wouldn't let it out. I think all that was instructed to be done for the TSB is pack the thing with dielectric grease like you did...hopefully you have fixed it.

thanks for the info, I filled it up and taped the outer edge so hopefully moisture will not get in there anymore.

I pulled the main plug that connects to the 7 pin you will have to take your mount off to get to it. Ive gotten to were i just clean it every oil change cause it throws the message about every 5000 miles anyway haha.
