3. Connect the Anode, (Non Striped) end, of the diode to one side of the Remote Starts enable switch.
4. Connect the other side of the enable switch to the Black/White enable input wire of the Remote Start unit.
The reference diagram below shows a typical GM B Body ECM reference wire and how it is to be connected to the
Remote Start Unit.
KEY IN SENSOR CIRCUITS:
If the vehicle you are working on does not have or you cannot locate the ECM reference wire, there are two alternatives
available. Although not preferred, the vehicle Key In Sensor may be reconfigured to allow a margin of safety and will
prevent the vehicle with a Mechanical Neutral Start Switch from starting in gear.
AUDIOVOX ADVISES THAT YOU MAINTAIN THE FACTORY CIRCUIT WHENEVER POSSIBLE. The following two
circuits may be used only if the above circuit is not available.
NOTE: When completing an installation using either of the following key in sensor circuits, if the operator inserts the
ignition key while the vehicle is running under the control of the Remote Start, the vehicle will shut down. This
must be explained to the operator as it is in contrast to the normal operation of a vehicle utilizing an electrical
neutral start switch and is inconsistent with the operators manual.
Additional information concerning Key In Sensor methods 1 & 2 are listed below and should be reviewed before
considering either alternative.
Method 1 will allow the safety required for the remote start unit and prevent the vehicle from starting while in any gear
other than Park or Neutral while the key is in the ignition cylinder however, if the key is left in the ignition switch and the
door is left opened, the added relay will be energized causing a 150mA drain on the battery.
Method 2 will allow the safety required for the remote start unit and prevent the vehicle from starting while in any gear
other than Park or Neutral while the key is in the ignition cylinder however, the original factory key in chime module will
not alert the owner that the key has been left in the ignition switch. In addition, this may also effect other warning tones
such as the light on reminder.
These situations should be carefully considered before altering the vehicle's wiring and must be fully explained to the
consumer.
