Here's a breakdown of the typical setup:

  1. Upfitter Switches: The physical switches in the cabin that you operate.
  2. Relay Box: Houses the relays that control the power flow.
  3. Fuses: Protects the accessory and the truck's electrical system from overcurrent.
  4. Accessory Power Output: The designated terminals where you connect your aftermarket device.
