ENGINE CONTROL SYSTEM 3-15
SUB BATTERY CABLE
The ECM power source is through the gray lead wire which sup-
plies power directly from the battery.
The white lead wire in the remote control extension harness car-
ries battery power to the ignition switch. When the ignition switch
is turned ON, battery power passes from the white lead wire,
through the ignition switch contacts to the gray output lead wire
to the ECM.
NOTE:
Ensure battery cable connections are clean and secure.
Failure at the battery connection will cause incorrect operation of
the ECM and starter motor cranking system.
