Installation:
An aftermarket center console is recommended for the mounting location.
This not only allows the driver to reach the controls easily, but also keeps
the unit safely out of the path of the vehicle’s SRS air-bag. Follow the
console manufacturer’s instructions for mounting. If a console mount isn’t
possible, a bail strap mounting kit is included for over or under dash
mounting.
Power & Ground Wires: RED: Power / BLACK: Ground
1.
Remove the front, driver’s side rocker sill plate and kick panel.
2.
Fold back the floor covering so that access is gained to the factory wire
harness routed under the driver’s seat.
3.
Insert the wiring harnesses into it’s port as shown below.
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 & be fused at the battery to carry that load. (See “Recommended Wire Sizes”)
4.
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. Be sure there are no components that could be damaged. Insert a grommet
in the hole to protect the wires.
5.
Route the RED and BLACK wires along the factory harness towards the battery and install a 25 amp fuse block (user supplied)
on the end of the RED wire.
NOTE:
Remove the fuse from the fuse block before connecting any wires to the battery.
6.
Connect the fuse block wire to the POSITIVE (+) terminal on the battery. There must not be more than 2 feet of wire between
fuse block and battery. The wire between the fuse and the battery is “unprotected”, don’t allow it to contact with any wires.
7.
Connect the BLACK wire to the factory chassis ground.
Speaker Wires: Orange & Brown
1.
Route the ORANGE and BROWN 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 ORANGE wire to the POSITIVE connection on
speakers #1 & 2.
3.
Connect the BROWN wire to the NEGATIVE connection on
speakers #1 & 2.
Horn Relay Wires: White & Grey
1.
Route the WHITE and GREY wires along the factory wire harness
and through the firewall at the same point as the RED and BLACK
wires.
2.
Route the WHITE and GREY wires to your vehicle’s horn relay. If
possible, follow the factory wire harness to this relay.
3.
Locate the wire that connects the vehicle horn to the horn relay and
cut it.
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 Re-broadcast (optional): 2 Blue wires
The two remaining BLUE wires are used to connect your two-way
radio’s external speaker for radio re-broadcast, an optional connection.
NOTE:
If your remote speaker is amplified (has a power amp circuit in
the speaker), Radio re-broadcast won’t work. Do not enable the radio re-
broadcast feature.
1.
Locate the two wires that connect the external speaker to the two-
way radio, cut one of them and splice one of the BLUE wires into
this circuit.
2.
Now cut the remaining speaker wire and splice the remaining BLUE wire into this circuit.
