We made it home without any disconnect messages. I did use small screw driver and bent outside portion of tt 7 pin probe inward. Will still try to check out the brake wiring. thanks again for the suggestions.

I had the same issue. Problem was a chafed brake wire on the trailer axle. Road vibration caused the wire to short-out on the trailer frame intermittently and I would get the "brake disconnect" signal.

Dielectric grease is actually a NON conductive grease. Best used to seal out moisture. Noalox might be a better choice. That's what I use on my plugs from the TT to the power post etc.

We had a similar experience disconnect warning that turned out to be a nearly cut electric brake wire, about one strand left. The wire was routed near the spring/axle u-bolt on the axle and the movement of the axle would short out the exposed wire giving the disconnect message. The cut was hard to see by just sliding under the trailer to inspect while on the road. The wire finally completely broke in two, giving a continuous disconnect message. Long story, short: check your brake wiring integrity and connections on your trailer.

The 7 pin plug seems secure and tigh.

I did spray the tt cord with a dielectric spray and when I hooked up for the first time follwing the spray, seemed to not have a good electrical connection. Made me wonder if that was a good idea to use this type of spray.
Thanks for the suggestions.

Use electrical contact cleaner then a dab of dielectric grease that has worked on my 2008 F450 over the years.

How secure is the 7-pin connector?

Agreed...

On some PINS you can take a very small screw driver and "open" the pin a bit. Do NOT over open, just a slight gap.


EDIT: Mark, how'd you get there before me :h
