This wire sends a negative pulse every time the remote start is activated and the alarm is disarmed. This can be
used to pulse the disarm wire of the vehicle's factory anti-theft device. Use a relay to send a (-) or (+) pulse to
the disarm wire as shown in the diagrams below. This wire can also be used as a special accessory output. (See
Feature Descriptions section of this guide.)

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 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. (See Finding the Wires You Need section of this guide.) 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
N N O O T T E E ! ! 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.)
