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 re-

viewed 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 start-

ing 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.

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

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

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

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

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

5) 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.

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

7) Connect terminal 87 of the relay to the Chime Module side of the previously cut wire in step 4.

8) Connect terminal 85 of the relay to the Drivers Door side of the pin switch wire previously cut in step 2.

NOTE:

  A second 4002 series diode may be required to maintain the integrity of the hood open, shut 

down circuit.  If this is the case, it must be installed as shown in the diagram above.  The anode (Non 

Striped) side must be connected to the Gray/Black wire of the Remote Start Unit.  The cathode (Striped) 

side must be connected to the hood pin switch.  If the hood pin switch is also used for an alarm trigger 

input, be certain to use the dual diode set up shown earlier in this manual.
