Wiring:
WARNING: All customer supplied wires that connect to the positive
terminal of the battery must be sized to supply at least 125% of the
maximum operating current and FUSED at the battery to carry that
load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
Siren Input (J7) - RED: Power - BLACK: Ground
1. Splice the 2 RED (Power) wires together, then extend this single
RED wire toward the vehicle battery. Splice the 2 BLACK (Ground)
wires together and extend this single BLACK wire toward the vehicle
battery. To pass the RED and BLACK wires through, you may have to
drill a hole in the firewall. Insert a grommet to protect the wires.
2. Route the RED and BLACK wires along the factory harness towards
the battery and install a fuse block (user supplied) on the end of the
RED wire. Remove fuse from fuse block before connecting any
wires to battery.
3. Connect fuse block wire to POSITIVE terminal on battery. There
must not be more than 2 feet of wire between fuse block and battery.
The wire between the fuse and battery is “unprotected”, do not
allow it to chafe and short to ground. Connect the BLACK wire to the
factory chassis ground.
Speaker (J6) - ORG, YEL, GRY & BRN
1. Route the ORG, YEL, GRY and BRN wires toward the vehicle
siren speakers, along the factory wire harness and through the
firewall at the same point as the RED and BLACK wires.
2. Connect the YELLOW wire to the POSITIVE terminal on
SPEAKER #1 and the ORANGE wire to the POSITIVE
terminal on SPEAKER #2. NOTE: For single speaker
installs use the YELLOW wire and cap the ORANGE wire.
3. Connect BRN wire to NEGATIVE connection on speaker #1.
4. Connect GREY wire to NEGATIVE connection on speaker #2.
Horn Relay (J5) - WHITE & GREY
1. Route WHITE and GREY wires along factory wire harness and
through the firewall at the same point as the RED and BLACK wires.
2. Route WHITE and GREY wires to vehicle’s horn relay. If possible,
follow the factory wire harness to this relay.
3. Cut the wire that connects the vehicle horn to the horn relay.
4. Connect the WHITE wire to the wire coming from the horn relay.
5. Connect the GREY wire to the wire coming from the horn.
Radio Rebroadcast (J5) (optional) - Two BLUE wires
The two remaining BLUE wires are used to connect your two-way
radio’s external speaker for radio rebroadcast (optional connection).
Note: If your remote speaker is amplified (speaker has a power amp
circuit), radio rebroadcast will not work and should not be used.
1.
Locate the 2 wires that connect the external speaker to the 2-way
radio, cut one and splice one of the BLUE wires into this circuit.
2. Cut the remaining speaker wire and splice the other BLUE wire into
this circuit.
