Connecting The WS295HFS1 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.
Locate your vehicle’s horn relay and route the WHITE and GREY wires to this. If possible, follow the
factory wire harness to this relay.
3.

Note:The two (2) remaining BLUE wires are used to connect your two-way radio’s external speaker
to the WS295HFS1 for radio re-broadcast. This is an optional connection and does not effect the
other operations of the WS295HFS1.
Note:Radio re-broadcast will NOT work with amplified remote speakers! If your remote speaker is
amplified (I.E.: contains a power amp circuit in the speaker assembly), do not enable the radio re-
broadcast feature.
1.
Locate the two wires that connect the external speaker to the two-way radio.
2.
Cut one of these wires and splice one of the BLUE wires into this circuit.
3.
Cut the remaining speaker wire and splice the remaining BLUE wire into this circuit.
Connecting The WS295HFS1 To A Remote Control-head (optional)...
The WS295HFS1 may be connected to an existing control-head, such as the Whelen PCDS-9 or equiva-
lent. This is an optional connection that enables the WAIL tone to be activated through the use of a PCDS-
9 button or switch. If this connection is not chosen,
cut the VIOLET wire and cap the remaining stub to
prevent accidental grounding of the wire.
