Wiper and Washer Switch

The
ignition supply is the main power source for the ECM; this supply will be disconne
cted by an inertia switch if the vehicle
is subject to a violent deceleration, as in a collision. The ECM has separate ignition and battery supply inputs. The battery
input maintains the ECM memory as long as the vehicle battery is connected.
