PSOM wire connector help

I have a wire connector that is hanging down under the gas pedal of my 1996 E350.

It is actually labeled PSOM and has a connector end. Its a single blue wire with a yellow stripe. I simply can't see anything to connect it to.

Is it a diagnostic line, or should it be connected?

It is the "Enable PSOM Programming Connector".
Just tuck it away some place.

If I'm not mistaken, it allows you to recalibrate the speedometer for different tire diameters or to correct accuracy. I think there is a limit to how many times it can be used. It should not be connected to anything.
