Note 1
The Fuse is essential to ensure that the ECU
is not damaged by reversed battery polarity
Note 2
To avoid the fuse blowing due to reverse
battery polarity use a diode activated relay
eg. Bosch 0 332 014 112
Note 3
The Ignition System Relay should be activated
using the Fuel Pump control wire to ensure
that the Ignition System is off when the engine
is stopped. Or use the Fuel pump relay to
to the Ignition System.
Note 4
The AUX1 Output can sink a maximum
current of 4 Amps.
The AUX2, AUX3, AUX4 Outputs can sink
a maximum current of 0.6 Amps.
