IMPORTANT WIRING INFORMATION
WARNING
The Vision® warning system is an advanced microprocessor based warning system. Unlike conventional light bars,
malfunctions and/or improper operation
WILL
result if proper installation procedures are not followed. Refer to the
accompanying diagram and pay special attention to the “DO & DON’T” list at the bottom of this page. To complete
the electrical installation, refer to paragraph 3-7.
DON’T
1.
DON’T...Use in-line fuses, solenoids, or relays to switch
power to the 10 ga. red wire. Unreliable warning system operation
will result.
2.
DON’T...Use solenoids or relays. Do not connect any other
products to this line. Unreliable warning system operation will
result.
3.
DON’T...Connect to any other chassis ground or ground
shared with any other product. Unreliable warning system
operation will result.
4.
DON’T...Connect to any black negative wire of the Vision
System. Unreliable warning system operation will result.
5.
DON’T...Use any wire smaller than 10 ga. or a circuit
breaker less than 50 amps. Unreliable auxiliary device operation
will result.
DO
1.
DO...Connect the 10 ga. red wire from the lightbar to one of
the two 50-ampere circuit breakers (installed as close to the
battery as possible and directly to the positive (+) battery termi-
nal). (Note: One 50-ampere circuit breaker can be used if the
auxiliary relays are NOT used.)
2.
DO...Connect the 18 ga. red wire from the six pin connector
(J1-Pin 2) to a point on the fuse block that is powered in run and
start positions (F13 on 1993 Crown Victoria and F18 on 1993
Chevrolet Caprice). Use an in-line 2A fuse.
3.
DO...Connect the 10 ga. black wire from the lightbar AND
the 18 ga. black wire from the six pin connector (J1-3) to the
fusible link at the front fender between the negative (-) battery
terminal and chassis ground. This is the ONLY chassis ground
allowed for these two wires.
4.
DO...Connect the green wire from the six pin connector (J1-
Pin 4) to chassis ground.
OPTIONAL AUXILIARY RELAY POWER:
5.
DO...Connect a 10 ga. wire to the load side of the other 50-
ampere circuit breaker. Route it through the hole lBAT on
the interface/relay unit and attach it to LUG 1 on the circuit
board.
