4. Parking brake switch
(1) When the parking brake lever is pulled, the
parking brake switch is turned on and the
“P” light on the LCD panel comes on. This
keeps the truck from moving.
(2) Voltage between CN1D-5 and CN1D-29
Parking brake lever pulled: 0V (switch
ON)
Parking brake lever released: 5V (switch
OFF)

6. BB relay
(1) Activates the back-up buzzer and light.
(2) When the F/R lever is placed in the R
position, the battery supplies voltage to the
CN1D-34 terminal. This activates the BB
relay, feeding power to the back-up light
and buzzer.
