Hey guys, got a 79 f150 4x4, nice and easy, what is this connector for? I can't find a wire around or under the truck that goes to it.

 

Backup lamp switch if on the transmission
Better picture?
Those backup lamp switches were on the shift tower

 

I'll get you a more zoomed out picture after work, and also try to get one of the pins inside of it.

 

If it's the backup lamp switch, there will only be 2 wires to it

 

here's a zoomed out photo as well as all the way in, looks like a 2 pin connector like you said.

 

You'll need to get down there under the truck with a flashlight, and look up to find the connector, if it's still there
The wires are only about 4 inches long coming out of that harness for the switch
Common to get unplugged
Looks like yours was hooked up not too long ago

 

I'm about 90% sure I didconnected it when I thought I was going to drop the tranny. The good news is, I'm actually dropping the tranny for real so if it's there I'll find it.
