The back of the CenCom Gold module features several distinct, color-coded, or keyed connectors. Wiring the system correctly requires mapping your equipment to the specific pins on these plugs. 1. Main Power Connections (Heavy Gauge Cables)
The following specifications are standard for the CenCom Gold: : Uses a heavy-duty 2-position Molex connector .
Route individual wires from your lightbar, flashers, and scenes to the output harness. Keep an organized log of which color wire maps to which output pin number; you will need this mapping during software programming. Step 4: Wire the Inputs and Ignition
Before diving into the multi-pin plugs, the system requires raw, fused power directly from the vehicle battery.
The ARM typically includes the following primary connections: Control Head Connection 20-foot, 8-conductor, 22-gauge cable to link the keypad to the ARM. Main Power (J12) : A heavy-duty, 2-position Molex or Anderson-style connector Red Wires (10 AWG) : Connect to a +12V source (fused at 40A each). Black Wires (10 AWG) : Connect to the vehicle's chassis ground. Output Capabilities High Current : 6 outputs (total max 60 Amps). Low Current cencom gold wiring diagram
The communication cable from the control head plugs into the designated port on the ARM, allowing for the "drag-and-drop" configuration.
Wires for the speaker(s) are typically found on a separate, clearly marked connector.
The CenCom Gold features a mix of high-power outputs for strobe/LED lights and lower-power outputs for signaling. High-Current Outputs (Outlets 1-3)
Inputs allow external vehicle triggers to change how the CenCom behaves automatically. The back of the CenCom Gold module features
The system uses multiple harnesses to manage power, inputs, outputs, and siren functions. A. Power Harness (Main Power)
: This eliminates the need for the driver to look down at the control head while navigating traffic, significantly improving safety and response time. Standard Wiring Overview
Comprehensive Guide to the Whelen CenCom Gold Wiring Diagram
Referring to the main power section of the : Main Power Connections (Heavy Gauge Cables) The following
Document which light is connected to which Output number (e.g., Output 1 = Front Lightbar Power, Output 2 = Left Alley Light ). You will need this roadmap when configuring the software. Step 5: Software Programming
This section of the diagram is often the most intimidating. It details how the control head communicates with the bar to activate specific modes (Mode 1, Mode 2, Take Down, Alley Lights). It’s a perfect example of —sending multiple signals over fewer wires. Reading this part of the diagram allows an installer to diagnose whether a broken alley light is a burnt bulb or a severed control wire.
