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 allowa margin
of safety and will prevent the vehicle with a mechanical neutral
start switch from starting in gear.
WE ADVISE 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 operator’s
manual.
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 affect other warning tones such as the light on reminder.
Note:
Additional information concerning key in sensor methods 1 and 2
are listed below and should be reviewed before considering either
alternative.
