Brake Lights
The other day I changed my pwr. steering pump, set the timing, and adjusted the choke on my 1978 Ford F150 351M with a c-6 auto LWB. I noticed that my brake lights were just staying on when i got through. I tapped the brakes, they were still on. I turned my lights on and off and the brake lights were still on. I turned on my hazard lights and off and they were still on. Now the only thing i can do is pull the fuse and turn my parking lights on in the day to slightly illuminate the lights in the rear so i dont get hit.
BTW, I even took the switch out and they were still on
whats up?

You have cruise control don't you?
You probably pulled the long black plunger type brake switch?
Try un-plugging the next switch up, that is connected to the pushrod for the brake booster.

well here I am, My truck is a 78 f 150,400 auto,no brake light , I dont have a diagram for the fuse box , that would help. all the fuses work. Im not sure how long the brake lights have been out. I was re wiring the trailer lights,and couldnt get any juice to the rear . I then started back tracking,Im now at the swith on the peddle. Im running out of places to look . Also my dash lights have never worked,maybe thats something to do with it #@%! Thanks Jaymie158@hotmail.com

The power for the brakes runs from the fuse in the fuse box, to the switch on the pedal, and then to the turnsignal switch.
See if you have power all the time on one of the brake switch wires. You should. Then activate the brake pedal, and you should have power on both switch wires.
If you have power going through the pedal switch when it's pressed, look for the same color wire up in the steering column. You should have power going up the steering column when the pedal is pushed.
Make sure the turnsignal switch is in the center. Go to the rear of the truck and make note of the color of the wires that go to the left and right brake lights. You should find these wires coming down the steering column. With the switch in the center position, when you press the brake pedal, both of these wires should have power. If you do not have power on these two wires, but you did have power going into the turnsignal switch when the brake was pushed, then your turnsignal switch is bad.
