OBDII Access?

On the Mav, from the factory is a cable is plugged into the OBDII access port that runs up to the dashboard, that has a 2nd short cable connected to it, that has a different type of rectangular multi female connector, not connected to anything.

When I plugged in my HUD display, I thought I was just removing a cap on the port to plug it in. I went for a test drive, and everything seemed normal with the Mav. When I got home, I noticed cable/connector hanging down, and determined the OBDII male part of the had been plugged in.

What is this cable for? :unsure: Can you safely run w/o it plugged in???

You have a good question. Perhaps, no one has a complete dash wiring diagram? Therefore, this is only a guess - and that would be that the multi female connector without any connections would be for the FORD technician to make additional diagnostics which are not possible with the OBD II port alone.

But in that case, it would be part of their tool kit in the shop, and not hardwired into each vehicle. Would add an unnecessary expense. There are multiple wires going somewhere up into the dashboard.

Update!!! I called my Service Dept., and was told it is for Lo Jack system installed by the dealership, so it can be left unplugged. They say it is for their insurance purposes, but it is redundant with the FordPass vehicle tracking, so it makes no sense.
