H2/4 GREEN/WHITE (-) factory alarm rearm
This wire sends a negative pulse every time the remote start shuts down or the doors are locked. This can
be used to pulse the arm wire of the vehicle's factory anti-theft device. Use a relay to send a (-) or (+)
pulse to the arm wire.
H2/5 GRAY/BLACK (-) diesel wait-to-start bulb 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. (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
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.)
