1999 WS cornering lamps

Cornering lamps are not working - I checked the bulbs on each side and both are good - found on the passegers side lamp it appears something has been unplugged. Not sure where the plug actually goes. Any ideas?

Not sure about the unplugged item. If you want to look at the colors on both wires on lamp socket, (on either side) we can make sure we are all on the same page.

Checked the wires - the lamp socket has pink w/red line & white w/red line...plug has red w/grey & grey w/red. Fuses are good to both lamps, I used a tester on the lamps and they appear to be getting juice. I can't figure out why they won't work. I thought the plug may have something to do with it. Since the lamps are getting juice I'm assuming they should work - or could the plug have something to do with it? Could it be some type of relay?

Keep in mind that Ford has constant 12v on external lamps ... its the negative side that gets switched. So the white/red wire should be "hot", the Pink/Orange is the negative line going to the Front Electronic Module (FEM).

Another poster found a break in such a wire.

The grey/red circuit may be #1455, which goes to such things as reversing lamps, left rear stop lamp, left rear turn lamp, license lamps, etc ..... fed by fuse #7 , and switched power relay #3, in box next to driver's left foot. Don't know why this circuit would be up front. ???
