Connections for Horn Ring Transfer (Cable Assembly P/N 1461907)

The default setting for the slide switch transfers the horn-ring activation of the siren amplifier in
Slide Switch 2 and 3. In Slide Switch 2, a press of the horn button activates the Manual tone. In
Slide Switch 3, each press of the horn button cycles through siren functions. In addition, the default
configuration for Slide Switch 3 is Siren Dependent Enabled, which restricts siren activation to the
slide switch position the you select. For example, if you press a button that is assigned a siren tone,
the tone only activates when you place the slide switch in the position that is programmed to be Siren
Dependent Enabled.
To enable horn-ring control of siren tones, obtain a SPST relay of enough contact-current capacity to
activate the vehicle horn:
1. Cut the wire that connects the switch for the vehicle horn ring to the horn or horn relay (Figure
3.6).
2. Splice the WHITE/YELLOW wire from the cable assembly (P/N 1461907) to the horn ring side of
the wire that you cut in step 1. Extend wiring with an 18 AWG lead or thicker.
