CONTROL HEAD ELECTRICAL CONNECTIONS
All control head leads may be extended with #22 AWG or larger lead wire.
Negative Connection (Black) - Connect to same ground or negative supply as amplifier.
Positive Connection (Red) - Connect to positive DC supply. It is recommended that the lead be connected to the accessory output of the fuse block. This provides additional protection of a fused input to the control head.
Lights (Yellow) - This lead may be connected to the dash lights or to the red power lead. Connecting to the dash lights will turn on the panel lights whenever the dash lights are on.
When connected to the red lead, make sure that the ignition switch controls the power to that connection. This prevents the panel lights from being continuously on.
Control (White) - Connect to white lead from amplifier. Route this lead away from radio transmitter antenna lead to prevent RF interference being fed to the siren amplifier.
Auxiliary Input (Green) - Used for Siren control. Performs same function as Siren button. Connect to a normally open switch or to horn ring circuit. Circuit may connect to either positive or negative. When connected to horn ring circuit, use a SPDT switch to connect horn ring to either vehicle horn or to manual control circuit.
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.
NOTE: Be sure to cut lead short if not used to prevent R.F. interference and insulate with electrical tape.
