Many installers wire a switch directly to an output pin. Wrong. The diagram shows that inputs (like Pin 6 Violet for Horn Ring) receive voltage. Outputs supply ground. If you connect 12V to an output, you will blow the internal solid-state relay.

Typical Terminal Label Summary (may vary by model)
Important: This is a general text guide. Consult the specific Cencom Gold model installation manual for exact terminal names, resistor values, voltage, and configuration steps.
Whelen CenCom Gold is a legacy siren and light control system that uses a single Amplifier/Relay Module (ARM) to manage vehicle emergency components. Wiring this system requires connecting several specialized plugs to the ARM, which serves as the central hub for power, inputs, and outputs. Key Wiring Connections
The system uses several distinct connectors for different functions: Main Power
: Uses a heavy-duty, two-position Molex® power connector to handle high current for the entire system. High-Current Outputs cencom gold wiring diagram
: Features a 4-position slide switch on the control head that typically manages one 40-amp and two 20-amp outputs. Siren Output
: A 2-pin connector that handles one or two 100-watt speakers. Accessory Inputs
: A 12-pin connector for various vehicle logical inputs (e.g., horn ring, brakes). Programmable Outputs
: A 9-pin connector for 10-amp fused outputs typically used for secondary lighting like grille lights or scene lights. Ferno Norden Denmark Core Component Overview Control Head
: Connects via a specific extension cable to the ARM. It includes 18 programmable backlit push buttons and a 4-position slide switch. Microphone
: Standard unidirectional microphone plugs directly into a 1/4" port on the front of the ARM. Programming Port
: A USB port located on the ARM allows for "drag and drop" configuration via Windows-style software without needing the control head connected.

Whelen CenCom Gold is a legacy siren and light control system designed for emergency vehicle upfitting. While it is an older unit, its primary "helpful feature" is its high degree of programmability
, allowing users to customize nearly any button to control specific outputs, sirens, or patterns. eLightbars Key Features of CenCom Gold Programmable Interface
: Includes an 18-button control head with a four-position slide switch (one 40-amp and two 20-amp outputs). Tactile Feedback
: Features membrane switches with a solid rubber overlay for moisture resistance, providing physical feedback during use. High Output Capacity
: The amp/relay module supports 6 high-current outputs (up to 60 amps total) and 16 low-current outputs. Backlit Buttons
: All buttons are backlit for nighttime visibility and come with an LED indicator to show active modes. Wiring & Support
Because this is a legacy product, finding official parts or diagrams can be difficult. Many connections utilize standard AMP connectors , which can be custom-built using parts from retailers like Typical Terminal Label Summary (may vary by model)

This is a comprehensive guide to understanding, sourcing, and using a CENCOM Gold wiring diagram. CENCOM (Central Communications) was a leading brand for aftermarket remote car starters and keyless entry systems, popular in the 1990s and early 2000s.
Critical Note: CENCOM Gold units are obsolete. If you are installing a new system, do not use this guide for modern wiring (CAN Bus systems are different). If you are repairing or removing an old unit, this guide is for you.
| Pin | Wire Color | Function | Notes | | :--- | :--- | :--- | :--- | | 1 | Green / White | Door Lock (-) Output | 200mA negative trigger | | 2 | Blue / Black | Door Unlock (-) Output | 200mA negative trigger | | 3 | Violet | Door Trigger Input (-) | Connects to dome light circuit | | 4 | Brown / White | Horn Output (-) | 200mA, requires relay | | 5 | Black / White | Neutral Safety Input (-) | Ground when in Park/Neutral | | 6 | Orange / Black | Trunk Release (-) | 200mA, requires relay |
Crucial for removal or troubleshooting: The CENCOM Gold always has a small push-button switch wired in-line with a thin black or black/white wire. This is the valet/programming switch.

When it comes to professional-grade warning light systems for police, fire, and emergency vehicles, the Whelen Cencom Gold stands as the gold standard (pun intended). This powerful siren and light controller allows first responders to manage complex lighting arrays, siren tones, and priority functions from a single interface. However, its sophistication comes with a challenge: the wiring.
For many installers—whether at a professional upfitting garage or a volunteer firefighter installing a system in their personal vehicle—the Cencom Gold wiring diagram is the most critical document in the installation process. Without it, you risk shorting circuits, blowing fuses, or failing to engage critical warning patterns when seconds count.
In this article, we will dissect the Cencom Gold wiring diagram in detail, explaining every pinout, harness connection, and best practice to ensure a safe, reliable, and legal installation.
