That connector is for a Daytime Running Lamp Resistor module.
The little plastic insert is a protective cap, which is removed when the DRL resistor module is plugged in. As seen in the OP's photo, there is also an unused silver colored speed nut that is prefitted into the sheet metal behind the head light (driver's side). This speed nut is what the DRL resistor module bolts into.
The resistor can get very warm, as it shunts the energy normally sent to the headlights for full brightness, and dissipates it into heat. The ABS brake module below the rubber flap in the background of your pic is a good distance away downward, and the driver's side battery is a good distance away rearward. So that resistor has a minimum of 2" clearance in a hemispherical zone surrounding it in that mounting position.
Canada requires DRLs. All the USA market Ex's are pre wired for them, but need two components to make them functional.
1. The DRL resistor that plugs into the connector in the photo above.
2. A relay, that typically plugs into a hidden relay connector that is underneath the passenger side airbag behind the glove box. The glove box must be emptied, so the sidewalls can be squeezed in to drop it all the way down. Then, the connector can be accessed. It is secured to the tubular support structure that spans the A pillars under the dash. There is an existing plug type of insert in the relay connector already that has a single jumper wire bypass. This plug must be removed and the relay installed in it's place.
Those are the two components required to complete the wiring of the DRL system already built into the Excursion.
Here are some photos of them.
On left, the jumper plug that gets replaced with relay behind glovebox, in middle, the relay, on right the DRL resistor that mounts behind headlight and plugs into connector the OP asked about.
