Power, speaker and signal connections:
•Telephone mute: Connect Pin 3 (grey) to the ”mute” connection of the vehicle’s telephone (if equipped) which
provides a ground signal when the phone is activated.
•Permanent positive: Connect Pin 4 (yellow) to the lead in the vehicle’s radio connector that provides +12VDC at
all times.
•Power antenna/amplifier turn-on: Connect Pin 5 (blue) to the lead in the vehicle’s radio connector that activates
the vehicle’s retractable or amplified antenna. If the vehicle is equipped with aftermarket or factory installed
amplifiers, connect this lead to the ”remote turn-on” lead of the amplifier(s).
•Illumination: Connect Pin 6 (orange) to the lead in the vehicle’s radio connector that provides +5 - +12VDC when
the vehicle’s parking lights are activated.
•Switched Positive: Connect Pin 7 (red) to the lead in the vehicle’s radio connector which provides +12VDC when
the ignition key is turned to the ACC or IGN position.
•Ground: Connect Pin 8 (black) to the lead in the vehicle’s radio connector which has a direct connection to the
vehicle’s chassis. Alternately, you may connect this wire directly to the vehicle’s chassis (bare metal).
•Reverse Lamp Signal: TrafficPro must receive a signal from the vehicle to determine whether the vehicle is moving
forward or in reverse. Pin 2 in Socket A (brown) must be connected to a wire which provides +12- +16 VDC when
the vehicle is placed in reverse and ground (0VDC) at all other times. The reverse signal wire in your vehicle
may be located at the transmission or shift linkage or at a reverse lamp.
Route a separate wire from the location where TrafficPro will be mounted to either reverse lamp in the rear of the
vehicle. Connect the wire to the reverse lamp connection which provides +12VDC-+16VDC when the transmission
is placed in reverse and ground (0VDC) at all other times. Connect the other end of the wire to pin 2, socket A in
TrafficPro’s connector (brown).
Alternately, you may connect the reverse signal wire to the reverse sensor on the transmission or shift linkage, which
provides +12VDC-+16VDC when the transmission is placed in reverse rather than the reverse lamp. If you choose
