My brake lights have been out for awhile and I thought that I had tried everything. New bulbs, new brake peddle switch, etc. Third brake light was working but not rear. Well fishing around back there today and noticed a green wire sticking out of the flex that holds all the wiring in near the rear lights. No voltage. Got my son to hold the brake and green wire has 12 volts. It has come loose from somewhere but I cant find where. Anybody see this wire sticking out on theres and see where it goes? Or does anyone have the brake wiring diagram?

 

ugh i have the same problem, and i've found that same damn wire, but can't figure out where it should go, i'm assuming another lead but it's no where to be found, and nothing is close enough to plug it into...

anyone could help it would be so great...

 

"I just had this problem with my 2000 F150. On my steering column, the upper and lower panels are held together by 3 screws. Removing these (and the tilt lever), I saw the top wire pulled out of the connector. Pushing it back in didn't work, since the shell locking mechanism would not longer hold the pin. I bought a new connector (comes with wire pigtails), and I carefully removed these with a small jeweler's screwdriver. Clicked the pins into the new shell, and plugged the new connector back in. Works great, now.

Shop manager at my local Ford dealer told me 98% of these problems are due to this connector on the multi-function switch (MFS). He even told me which pin would be the culprit. Turns out most problems are caused by tilting too far, since there's not enough slack in the wire bundle up to the connector. I caused my problem by dropping the steering column onto the front seat when I had the dash out. Went 2 months with no one telling me my brake lights were out."

this is what fixed mine.

 

Here is the wiring diagram.
