just a comment. the vast consensus on all RV forums is that a vehicle with a towing capacity of only 3500lbs., is a very poor choice for towing a full-height trailer.
both from a safety standpoint and a vehicle durability standpoint.

yes, there's be a few naysayers who say that it's no problem. but the vast majority of the experienced, will point out that a full height trailer's frontal area, will exceed the vehicle's specs. the air resistance of a full height trailer will stress the poor v-6 drivetrain trying to pull it through the air.
a good headwind or any real mountains will not be good for the vehicle's life.
then you add the trailer's length, vs. the vehicle's very short wheelbase and there's that danger.
and finally, nearly all trailers with a GVWR of 3500lbs., will have extremely low cargo capacities, which ensures that the tow vehicle will always be towing at its max capacity.

3. F85B- 14A348 P260H HARNESS TO THE Expedition
All of the above should be kit that came with the Expedition located in the glove box:
Are these other harnesses usually already installed from the factory (with tow package)

The brake controller harness is to be attached to 3. F85B- 14A348 P260H HARNESS TO THE Expedition. There should be a Plug up under the dash to the right of the steering column that the above harness should plug into.

I just ordered the Tekonsha 3035-P harness, it looks like it should just plug into the open connector near the obd-II port. That should be it?

I'm thinking of just using velcro to attach it to the panel. Is there anything required when mounting (must be level?)
