2006 E-350 6.0 PS Brake Lights OUT

I have read almost all the posts on here about this problem with all 3 brake lights out.

The switch closes when you push the brake pedal. Checked it with an ohm meter.

The plug that attaches to the brake switch has 12v on one side and 3.85v on the other. Is this correct?

The trailer plug was very corroded, so I cut it off and put wire nuts on it until I can replace it.

Since it's a van, it looks like the wiring comes down through the inside along the drivers side.

If anyone has a wiring diagram I would most certainly appreciate it. tga2@live.com

The light green/red wire at the brake on/off switch should have 12v. This is supplied by fuse 11 in the interior fuse panel.
Once you apply the brakes, the dark green wire is energized at the brake switch. It then travels to fuse 39(10 amp) inside the interior fuse panel and becomes a light green wire that travels back to the rear brake lamps.
You also may want to remove and clean the black wire(G400) that controls the ground side of the lamps. My schematic describes G400 as being located "at left side of vehicle rear end".
Hope this helps...
