Each output on the Cencom Gold is rated for 2 to 5 amps (check your specific model year diagram). If you try to run six 100-series LED heads from one output (total 6 amps), the system will thermal-shut down. Use the Cencom to trigger an external automotive relay (Bosch style) for high-draw devices like older strobes or halogen work lights.
This is the thick wire bundle.

The complexity of the Cencom Gold wiring diagram shines here. The unit uses negative switching (ground switching) for most outputs. This means the computer sends a ground (-) signal to turn a light on, while the positive (12V+) is supplied directly to the lighthead. Each output on the Cencom Gold is rated

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.
