I doubt it's the fog light as there's only 1 plug on the drivers side. None on passenger. And my car doesn't have fog lights. It does look like it comes in with the headlight lines though. I drew an arrow where they enter.
So it is for a fog light? Why is there not one on the passenger side? I looked for cut wires and couldn't find any. I just don't know why someone would rig those wires together like that. The thing I removed was the correct plug but it didn't look like it could have ever been a light bulb.
The wires do not look long enough for a fog light
Only a few connectors that look like that on a Ford
Blower motor. Electric cooling fan. Headlight and Fog light
I'd have to look at my car but I believe there would be a harness from that plug to the fog lights,
the plug in the first couple pics looks jacked up, it's spliced (I use that term loosely) into wires, those the ones that go under the battery?
