Ford Bronco SUV: Get Hooked Up

Part of the fun of driving a Ford Bronco™vehicle is the ability to customize. If equipped, available Auxiliary Switches with Pre-Run Accessory Wires are directly connected to the fuse box and allow owners to easily hook up their lights, radios or any other electrical device they deem necessary.

What Are The Auxiliary Switches Inside Your Ford Bronco SUV?

The auxiliary switchboard on the overhead console makes aftermarket customization easier with six prewired switches connected to the power distribution box. The six switches:

  • Can be customized to control additional functions
  • Operate only when the ignition is in the On position, regardless of whether the engine is running or not
  • Feature indicator lights that illuminate which switch, thus which device, is in use

How To Locate The Auxiliary Switches Inside Your Ford Bronco SUV

The switches, located above your head, are labeled AUX 1 through AUX 6. When using them for an extended period of time or when you are using high-current accessories, we recommend that you leave the engine running to maintain battery charge.

How To Locate The Auxiliary Switch Wiring Inside Your Ford Bronco SUV

There are six powered circuits and five non-powered circuits. See your Owner's Manual (page 303) for details on how to locate and identify fuses.

How To Tie Into Auxiliary Switch Wiring

Copy: When we designed your Bronco SUV, we designed with off-road enthusiasts and their love of accessories in mind. That means we did all the auxiliary wiring for you.

The six switches over your head lead to a power distribution box in the engine compartment. From there, there are five circuits that run to different parts of your Bronco vehicle:

  • One goes to the front grille next to the headlamp
  • Two circuits go to the passenger compartment behind the glove box
  • One circuit goes above the windshield by the passenger visor
  • One circuit goes to the passenger-side rear quarter panel

Now all you have to do is wire your accessories using the color-coded wires, making sure that the coloring is consistent as you connect from your power distribution box to the final circuit destination.
