Engine Wiring Harness
The following lists the engine and vehicle side connections. Optional circuits are described in the 'System Features' section
below: NOTE: A Malfunction Indicator Lamp (MIL- sometimes called a "Service Engine Soon" light) is mounted inside
the fuse/relay center. A redundant MIL output is also available in the harness near the pedal module connector. It is
recommended that a MIL also be installed in a visible location in the passenger compartment. This circuit requires any
12v low current light and an ignition 12v power source. The ECM MIL output supplies the ground for the circuit.
