auxiliary harness (H2) wire connection guide
This wire provides 200 mA programmable output. (See Feature Descriptions section of this guide.)
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.
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.)
H2/3 GRAY/BLACK (-) diesel wait-to-start bulb input
H2/2 GREEN/WHITE factory rearm output
H2/1 VIOLET/BLACK (-) channel 4 output
