Passenger Compartment Connections
Control Unit and Antenna
The Polaris 4 control unit must be installed inside the vehicle. Under no
circumstances should the unit be installed under the hood or other similarly
hostile environment.
1.Select an area behind the dash to mount the control unit using wire ties, but do not
permanently affix it until all wiring and testing is complete.
2.Run the antenna either up the window pillar or under the dash, away from metal. Do not
fold the excess cable or antenna wire. Do not make hard, sharp bends.
Door Trigger/Interior Light Supply
Door triggers on most autos are negative (except most Rolls-Royce and Ford autos). To
determine door trigger polarity, use the following procedure:
1.Find the wire coming off the rear of the vehicle door switch.
2. Connect the negative voltmeter lead to ground.
3.Find the one wire that shows +12 volts when the switch is pressed in and 0 volts when
released. This is a negative trigger door wire.
4.If you don’t get the indications noted in step 3, find the one wire that shows 0 volts when
the switch is pressed in and +12 volts when released. This is a positive trigger door wire.
5.Connect the system’s thin GRAY wire to the door wire.
6.If the door trigger is negative, no further installation is required.
7. If the door trigger is positive, program for positive using the Installer-Programmable
features matrix on page 17.
8.If dome light supervision is desired, connect the relay as shown in the Polaris 4 diagram.
nConnect the BROWN/WHITE wire to terminal 86
nTap a wire in to the RED/WHITE wire (+12V) and connect it to terminal 85.
nTap a wire into the GRAY wire and connect to terminal 30.
nConnect terminal 87 to positive if the door trigger is positive (+12V RED/WHITE
wire), or connect terminal 87 to negative if the door trigger is negative.
