This is the first time changing oil on this new to me 2013 3.6 Outback. Right next to the oil filter there is an electrical connector that is attached to a small metal bracket. The bracket does have a hole in it and, presumably, should be fastened somewhere but it's just dangling right against the unibody. The connector has two wires (yellow and black). The end of the connector has a plunger on it that can be pressed in but it appears to be spring loaded to pop back out. Wires from the connector come up behind the air box and then join the main harness to travel along the firewall. Anyone have a clue what this is/does? I'll try to get a picture of it.
