Brake Switch
When the brake light switch is activated, the Jeep/Truck Engine Controller (JTEC) receives an input indicating that the brakes are being applied.
After receiving this input, the JTEC maintains
idle speed to a scheduled rpm through control of the
Idle Air Control (IAC) motor.
The brake switch input is also used to supply/deny power to the speed control servo solenoids.
