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.

METHOD 1

Circuits may be used only if the above circuit is not available.

To connect to the key in sensor as shown in method 1:

A. Locate the control wire that connects the drivers door pin switch to the key in sensor switch.

B. Cut this wire and connect the ignition cylinder side to chassis ground.

C. Locate the key in sensor switch wire that connects the chime module to the ignition cylinder .

D. Cut this wire and connect the ignition cylinder side to terminal 30 of a P&B VF45F11 or equivalent relay.

E. Connect the cathode (striped) side of a 4002 series diode to this same wire, and connect the (non striped) side to

the negative shut down safety wire (Gray / Black) of the Audiovox Remote Start Unit.

F. Connect terminal 86 of the relay to a fused +12 volt constant battery source.
