Hi guys,
I got a Hitch Mounted Cargo Box (https://www.stowaway2.com/hitch-cargo-boxes) for my 2020 Expedition Max. The box connects to the 4-pin trailer wiring connector (for the tail lights and the license plate light).
Now the problem is, when I connect the 4-pin trailer plug, the Expy says "Blind spot & cross traffic alert deact. Trailer attached".
I'd really like to get at least BLIS working. I can live without the cross traffic alert, but we are about to go on an about 26-hour drive, switching drivers, and the wife swears by the BLIS system.
Here is what I am doing. Starting with all trailers deleted, ignition off and cargo box electrical cable connected to the hitch electrical connector.
1) Turn on the ignition. The console says "Blind spot & cross traffic alert deact. Trailer attached".

2) I OK out of it. Select "Towing", then "Trailer Setup". It says "Press OK for trailer options".

3) I select OK, then "Add Trailer".

4) It asks me to name the trailer. I name it "a".
5) It asks if I want to "Add Trailer Blind Spot" and I say "Yes"

6) It asks "Is the width less then 9ft and length less then 33ft?". I say "Yes".
7) It says "Enter Trailer Length". I leave it at the default 18 ft (previously tried 3ft and 6ft, without success, so tried to leave it at default 18ft this time). Press OK.

8) The console says "Trailer Blindspot Measurements Have Been Saved".
I rejoice and press OK.
No dice. BLIS is still off.
