Mystery Plug
1987 F-250 diesel. It feeds back into the headlight/park light harness. Could it be a 'plug and play' plug for plow lights? Did they have those back then?

Looks like the head light connection. Are you saying there are 2 of them? Don't know if that year came equipped with auxiliary plow light connections.

The headlights and parking lights are already hooked up. This plug is just lying in the space down below.

I swear when I did a headlight relay harness, I had to leave one of my headlamps unplugged. All I can make of it.
