That plug is for the Canadian Daytime Running Lights that only the Canadian cars use.
In Canada, any car built after Dec 1, 1989 was required by law to have Daytime Running Lights and rather than manufacturing 2 different wire harnesses Ford just made one and used a shorting plug on the US cars.
Meaning no car in the United States has the actual hardware/device/relay/solenoid or whatever it is that plugs into that, to make the daytime running lights work and the reason the plug is not connected to anything.
You'll notice the shorting plug cap that is installed will have two pairs of contacts to complete the circuit since the module itself is not installed.
Without the cap or if you eliminate the wires the high beam indicator and brake light indicator (e-brake and fluid) on dash will not work.
Of the 7 wires only 4 are used; so if you want to delete the wire harness you can. “BUT” you have to connect the Grey/White wire to the Light Green/Black and the Pink/White to the Light Blue/Black for the high beam indicator and brake light indicator on dash to work.
The rest of the wire just cut back in the harness.
