Connect this wire to the second ignition wire in the vehicle.
auxiliary harness (H2) wire connection guide
This wire sends a negative pulse every time the remote start is activated. 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.)
Relay for Negative (-) Disarm Wire
Relay for Positive (+) Disarm Wire
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 Wait-To-Start Bulb Wire For Diesels
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 indi-
cator and the ECM. (See the following diagram for details.)
