horn, channel 6 harness (H4) wire
connection guide
This wire provides a (-) 200mA output whenever the transmitter button(s) controlling Channel 6 is pressed. (see
also the Feature Descriptions section and previous channel 5 description):
IMPORTANT! Never use this wire to drive anything but a relay or a low-current input! This transis-
torized output can only supply 200 mA, and connecting directly to a solenoid, motor, or other
high-current device will cause the module to fail.
This wire provides a (-) 200mA output to the horn when programmed.

neutral safety switch interface
Some vehicles do not have an electrical neutral safety switch. Instead, a mechanical neutral safety switch that
physically interrupts the starter wire is used when the vehicle is in any drive gear. If the remote start is inter-
faced before this switch, it will provide protection from starting in gear. However, some vehicles combine the
column shift mechanism and the mechanical neutral safety switch into one mechanical part. In these vehicles,
it is impossible to interface the remote start system before the neutral safety switch. With this type of vehicle,
if the car is left in a drive gear and the remote start system is activated, the vehicle will move and may cause
damage to persons or property.
According to available information, the only vehicles currently manufactured this way are most General Motors
trucks, sport utility vehicles and column shifting passenger cars. Available information also indicates that pre-
1996 Dodge Dakota pickups with 2.5 liter motors are manufactured this way as well.
GM vehicles that have the neutral safety switch built into the column shifter can usually be identified by a purple
starter wire. Typically, vehicles that use an outboard mechanical switch use a yellow wire from the ignition switch
