Hello
I bought a new LED high mount light off of Amazon for my 2005 Ford Ranger truck watched some YouTube videos on removing and replacing it. The old light was only brake light but the new light has brake and cargo lights the brake light works great but I don’t have any cargo lights I do have interior light switch on and it works fine but still no cargo lights please help what do I need to do to get the cargo lights to work.

 

You need to run a wire for the cargo lights. You're gonna have to tie it in to the dome light circuit.

Here's a how-to.
