Relays offer an efficient and reliable means of switching high currents with minimal power loss. Auto manufacturers and professional car builders recognize this and have been using relays instead of bulky switches to improve the quality and reliability of automotive electrical systems for decades. The Power Center utilizes high quality relays to distribute power to various vehicle loads. This means no more time-consuming mounting and wiring add-on relays.

The Super Duty Power Center ... Key features:

  • Power feed and outputs are connected to the Power Center through heavy duty stud terminals for simple, bullet-proof connections.
  • Dedicated relay for high current solenoid type shifters
  • Also supports cocking style "spring" shifters and pneumatic solenoid shifters
  • Status LEDs provide instant diagnosis of blown fuse or faulty output
  • Rubber mounted for long term durability and protection against severe vibration and tire shake
  • Rails along the sides allow wires to be secured to panel with cable ties for extra vibration resistance
  • Reverse battery protected.
  • Compact size: 8" x 5 1/2" x 1 3/4" (LxWxH) makes mounting easy.

The Super Duty Switch Panel includes 6 switches that control Ignition, Start, Fuel Pump, Water Pump and Fan, Interior Lights, Tail Light, and Auxiliary power. An attached 8 ft cable attaches to the Power Center. Other cable lengths are available by special order. Chose from a variety of finishes including Gun Metal, Silver, Gloss Black, Carbon Illusion, and Chrome (some at extra cost).

The Fuel Pump switch will operate only when Ignition is on. The Water Pump can be operated alone, but the Fan switch turns on both the Fan and Water Pump. The Water Pump switch is generally used for gradual engine warm-up or cool-down whereas the Fan is used for max cooling.

The Interior Switch is used to turn on only the LED lamps on the back of the Switch Panel. In the down position, the Lights Switch is used to turn on the tail light but does not turn on the Interior LED lights.

An optional Switch Panel enclosure securely mounts to 1-5/8" and 1-3/4" roll bars. Holes in the bottom allow the interior lights to shine through. Durable powder coat satin black finish with stainless steel fasteners. Switch Panels are usually mounted on the front halo bar where a top cover for the roll bar mount is not needed. For this reason the standard roll bar mount does not include a top cover but can be ordered at extra cost.
