A: The single ARM reduces the need for complex, messy relays, making the wiring cleaner and easier to diagnose if a problem occurs.
Wire lights and sirens to the designated output harness. Ensure wires are properly shielded and secured.
: This feature allows the CenCom Gold to power on and off automatically with the vehicle's ignition key. Locate the RED/BLK wire at Connector C, Pin 14. Connect this wire to a suitable ignition-switched power source at the vehicle's ignition switch. cencom gold wiring diagram
Run heavy-gauge (typically dual 10 AWG or single 4 AWG, depending on the harness configuration) red wires directly to the positive battery terminal. You must protect these lines with an in-line master fuse block rated at 40 Amps per main input line .
WeCan lightbar works but cannot change patterns. Diagnosis: You have a data bus termination error. The diagram will show a "termination plug" or resistor required at the end of the WeCan chain. Ensure the correct plug is inserted into the unused WeCan port on the Cencom Gold. A: The single ARM reduces the need for
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)
| Pin | Wire Color | Function | Technical Note | | :--- | :--- | :--- | :--- | | 1 | Red (10 AWG) | | Connect directly to the positive terminal of the vehicle battery with a 40A fuse within 6 inches of the battery. | | 2 | Black (10 AWG) | Chassis Ground | Connect to the vehicle chassis. Do not daisy-chain with other grounds. | | 3 | White or Yellow | Ignition Sense (Switched) | Connects to a fuse that is only live when the key is in "Run" or "Accessory" to automatically shut down the system. | | 4 | Orange | PA (Public Address) Speaker + | Positive lead to the 100W Whelen speaker under the hood. | | 5 | Brown | PA Speaker - | Negative lead to the speaker. | | 6 | N/A | (Reserved) | Usually for diagnostic programming. | : This feature allows the CenCom Gold to
Connect the 10 AWG red/black wires to the battery and chassis ground.
Use cable ties and loom to keep the wiring harness away from moving parts (steering columns, pedals) and heat sources (exhaust).
