The physical connections for the CenCom Gold all terminate at the Amplifier/Relay Module (ARM). Understanding the pinout of the various connectors is fundamental to a successful installation. The ARM features heavy-duty, two‑position Molex power connectors designed to withstand vibration and rough handling without accidental disengagement. The following sections detail the purpose of each wire group, drawing from official Whelen documentation.
Typically wired to the vehicle's transmission park-switch circuit. This automatically mutes the siren or changes the light flashing pattern when the vehicle is shifted into Park.
The ARM features six high-current outputs designed for heavy loads like lightbars and floodlights. 20 Amps Max (typically fused at 10 Amps). Output #3 & #4: 10 Amps Max.0;25a; cencom gold wiring diagram
: Total of 6 outputs (2 at 15A max, 4 at 10A max). Low Current Outputs : 16 outputs limited to 2A max each .
Connecting these high-current outputs directly to a modern car's data network will destroy the Body Control Module (BCM) , costing $1,000+ to repair. The physical connections for the CenCom Gold all
: Linked to the ARM via a 20-foot, 8-conductor, 22-gauge cable .
The system handles both (for lightbars, perimeter lighting, and auxiliary equipment) and low-current inputs/outputs (for ignition triggers, radio rebroadcast, and horn ring transfers). CenCom Gold Connector Pinout Diagrams The following sections detail the purpose of each
:
The system can drive one or two 100-watt speakers. Use dedicated siren driver outputs to ensure proper audio delivery. 3. Custom Controls and Inputs The CenCom Gold stands out for its flexibility.
