How to Wire Your Light Bar to Your Ford Upfitter Switches 

 

 For those that have a 2007+ Ford F-series you've probably always noticed the switches to the left of the steering wheel that seem to not control anything. Those are the Ford up fitter switches that were designed to allow for auxiliary control. 

 

 Installing a Black Oak LED light bar or LED POD in later model Ford F-Series Super Duty Trucks with auxiliary Upfitter switches is a breeze.

 

Choosing the Right Size Ford Upfitter Switch

There are three Ford Fleet bulletins covering the details of Ford Upfitter switches for various model years:

Refer to these bulletins to determine the location of the Aux switch wires, insulation colors and amperage capacities of each switch.

For example, model year 2008 Aux 1 and Aux 2 30A switches are yellow and green/brown, respectively. Aux 3 is violet/green with a 10A rating and Aux 4 is brown with a 15A rating. Thus, the Black Oak Curved 50 inch light bar can use Aux 1 or Aux 2 switches, whereas the 20 inch light bar with double rows of 5W LEDs would connect to Aux 3 or Aux 4 switches.

 

Installing a Black Oak LED Light Bar to Upfitter Switches

Simply disconnect the leads from a Black Oak wiring harness at the relay and set aside the relay, fuse and switch. Pass only the hot lead through the truck firewall to the correct blunt-cut Aux switch lead. The negative lead should be connected to a ground point inside the engine compartment.
