H2/7
GRAY/BLACK (-) DIESEL WAIT TO START INPUT
Connect this wire to the wire in the vehicle that sends the signal to turn on the
WAIT-TO-START bulb in the dashboard. In most diesels the wire is negative
(ground turns on the bulb) and the GRAY/BLACK wire can be directly connected
to the wire in the vehicle. If the vehicle uses a positive wire (12V to turn on the
bulb) a relay must be used to change the polarity.
The system has a programmable onboard timer (See Feature menu #3, feature
#9) so it is not mandatory to connect to the wait-to-start wire in the vehicle.
Note: A 1-amp diode must be installed in line on the factory wire between the
wait-to-start indicator and the ECM. (See the following diagram for details).
