METHOD 1
Key In
Chime Module
Connected to (-) Negative
Safety Input Wire
White/ Black
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 4003 series diode to this same wire, and connect the (non
striped) side to the negative safely input wire (WHITE/ BLACK) of the Remote Start Unit.
F. Connect terminal 86 of the relay to a fused + 12 volt constant battery source.
G. Connect terminal 87 of the relay to the Chime Module side of the previously cut wire in step D.
H. Connect terminal 85 of the relay to the Drivers Door side of the pin switch wire previously cut in step B.
Note: A second 4003 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 Stripped)
side must be connected to the WHITE/ 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 assembly packaged with the Remote Start Unit as shown in this installation
guide.
METHOD 2
Connected to (-) Negative
Safety Input Wire
White/ Black
To connect to the key in sensor circuit as shown for method 2:
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 the Remote Start Negative Safety Shut down wire
WHITE/ BLACK, using a 4003 series diode as shown above.
Note: A second 4003 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 WHITE/ 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 assembly packaged with the Remote Start Unit as shown in this installation guide.
AFTER THE CONNECTION OF THE NEUTRAL START SAFETY WIRE AS INDICATED IN ANY OF THE
PREVIUOS ALTERNATE CONFIGURATINS, THIS CIRCUIT MUST BE TESTED FOR OPERATION.
Retest by following the steps outlined in the NEUTRAL START SAFETY TEST shown in this manual.
