I'd have to check the stop lamp switch. It should be activated by the brake pedal arm. W/o being able to look at your vehicle at your vehicle, I can't tell you how to get at it? The lite green wire in diagram should not be hot unless you press the brake pedal. If you lift up on brake pedal does the brake lamp go out? If it does go out, maybe you can adjust brake switch, possible problem with brake switch or connector?
The voltage for brakes is wired through multifunction switch, that is something else to check. At the rear, your brake lamps and turn signal use the same bulb filament, just not at the same time.

Need diagram for f150 1976 wire attachment to break pedal, replaced slave cylinder abad now lights are on constant.

Mcmom, Either your brake pedal is not coming up far enough to the brake switch, or the brake switch is faulty. You may still have air in brake system not allowing pedal to come up high enough to contact switch, pull brake pedal all the way up and have a second person see if brake lights go off.
Links below to show brake switch location and show how brake pedal arm should come all the way up to turn off brake lights.

I need a diagram for the brake vacuum switch on a 1988 F150

Look at the brake pedal and follow it up under the dash. The switch is mounted to a bracket. The switch is the only thing touching the brake pedal arm.

My 2006 f150 has new brakes and rotors,fluid full but my dash brake light stays on. Soon as you start it and the whole time you drive. Also the cruise quit too. Once the light went off then the cruise

This sounds like the brake light switch or the control switch on the brake pedal is bad or loose. Check under the dash above the brake pedal there should be one or two switches that tell the brake lights to come on and the cruise control to shut down.

Brake lights stay on after engine is turned off

The brake lights have power with the key off, so you have just one thing that is causing this, a defective brake light switch. The brake light switch is located at the top of the arm the brake pedal is attached to under the dash, you will need to remove the lower panel under the dash to see it. The part is cheap and requires little skill to replace. Below is a picture of the part.

RX-7 1988 does not have brake lights and blinkers do not work although you can hear the blinker under the dash.

Your Boo switch is open. Look for the brake pedal pivoting point, which is going to be almost under the dash board. The Boo switch is attached to the pedal, you should be able to see the plug and wires going to it. Disconnect the plug and remove the switch from the pedal assembly. Replace it. That should take care of both problems.

Brake lights stay on whether the ignition is on or off

Hi Friend:

Your Brake Light Switch is Faulty or Damaged, You'll locate your Brake Light switch under the Drivers side dash,Attached to your Brake Pedal arm.

Its not an expensive Part Probally not over $10.00,

It has a couple wires running to it and is normally mounted on a small bracket, and has a nuts or a Clip holding it on to the Brake pedal arm.

This should get your Brake Lights out when your not pushing the brake pedal, While your under Dash ALSO make sure the Brake pedal return spring is Attached to the Brake pedal arm and is Pulling the brake pedal UP when its released.

Please let me know how my Solution helped you,By Voting on the Solutions i've given you.

Brake light switch staying on flattening battery

The switch is located above the brake pedal, about six inches. Sometimes there is a rubber stopper attached to the brake pedal assembly that closes the switch. If it is missing, nothing pushes the switch. Put a small bolt through the hole with a nut.
