Body Wiring Harness and Components
for your 1990 Pontiac Grand Prix


The body wiring harness and components of your Pontiac Grand Prix are vital to the operation of the brake system. As the source of power, these cables deliver the signal that either engage or disengage the brake. It responds to commands from the automobile's computer, which are initiated as your foot compresses the brake pedal.


The brake system on a Pontiac Grand Prix impacts a driver's ability to remain safe while on the road. Engaging the brake pedal for deceleration or a total stop carries an expectation that the brakes will respond and obey the command. By replacing worn-out harnesses and components, you can make sure this happens.
