tive ground pulses on the white/blue wire for the remote engine start to activate or to deactivate. The same holds
true for the remote control activation when set to a two pulse setting it is necessary to press the
button
twice for the remote engine start to activate or deactivate.
NOTE:
When the activation pulse count can be programmed to 1, 2, or 3 pulses when changed it
will affect both activation inputs; the White/Blue wire and the remote control activation.
Connect this wire to the wire in the vehicle that sends the signal to turn on the WAIT-TO-START bulb in the dash-
board. In most diesels the wire is negative (ground turns on the bulb) and the GRAY/BLACK 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. (See
Finding the Wires You Need
section for testing procedures.) Here are some
common colors of this wire:
■
Chevrolet and GMC trucks: Light Blue or Dark Blue
■
Ford Trucks: Black/Pink
■
Dodge Ram Trucks: Orange/Black or Black/Orange
NOTE!
A 1-amp diode must be installed in line on the factory wire between the wait-to-start indi-
cator and the ECM. (See the following diagram for details.)
