“I bought a new controller for my PS4. How do I connect my PS4 controller?”
You’ll need to connect the new PS4 controller to the PS4 using a USB cable while the PS4 is turned on. Do the same thing with additional controllers as well.
This process is called “pairing” or device registration if you want to get all fancy. Each controller is will be assigned a specific color (which depends on the order each controller was turned on).
