I have found ones for Camry, Highlander, and Corolla. They show two different slots to insert the paperclip. Turn car OFF.
Why does my car not start when the brake light is bad?
The car may also not start because, in automatic transmission vehicles, the car needs to detect that the brake pedal is pressed. If the brake light switch is bad, the Engine Control Unit (ECU) will think you are not pressing the brake pedal, therefore not allowing you to start the car.
Are there brake lights on a 2003 Electra Glide?
New to the forums here with a question. I just bought a 2003 Electra Glide Standard. I noticed the brake light wasn’t working with either the foot pedal or the lever on the handlebar. The lights are on while running but do not get brighter when using the brakes. So far I: -jumped the 2 connectors that attach to the rear brake light switch.
