Adding accessories to your Ford truck is a great way to customize it to your needs. However, wiring these accessories can be a daunting task. That’s where upfitter switches come in. These pre-wired switches allow you to easily add electrical accessories to your Ford truck without the headache of wiring them yourself. In this article, we will discuss the 2012 Ford upfitter switches wiring diagram to help you understand how to properly install and use them.
What are Upfitter Switches?
Upfitter switches are pre-wired switches that Ford provides in their trucks for adding electrical accessories. These switches are located in the center console and come in different numbers, depending on the truck model. For example, the 2012 F-150 has four upfitter switches. These switches are designed to handle heavy loads and are fused individually to protect your truck’s electrical system.
