Sensor Wiring Harness
WARNING: To prevent serious personal
injury, possible death, or damage to the engine or
vehicle, disconnect the main negative battery
terminal before removing or installing any
electrical components.
CAUTION: To prevent engine damage, make sure
the key is in the OFF position before unplugging the
connector or relay for the ECM, IDM, and EGR drive
module. Failure to turn the key to the OFF position
will cause a voltage spike and damage the electrical
components.
CAUTION: To prevent engine damage, do not tug on
any wiring harnesses while trying to remove them. If
resistance is felt, find the source of resistance and
free up any connectors or clips that are caught before
proceeding.
