How many wires go to it and what colors? It could just be a test mode connector if its behind the kick panel on passenger side
If you zoom in you can tell there are only 10 pins to it. The others are blanks, I thought the same thing when I saw it. But id agree with Silverton that its the Canadian DRL module.That's a 16 pole connector, I would think it goes to the fuel pump assembly. It's not on the chart/diagram posted by Silverton, but that's not the first time I've seen unlisted connectors.
