I purchased a Magnum Truck Rack with built in brake/turn lights and back up lights. They provide a wire harness that you remove the feed plug from the trailer plug and plug their harness in which has a Y for the original plug to plug into. I have my brake/ turn lights but no back up. I am assuming it uses the trailer backup light function. I found a fuse for trailer back up lights and it is good. Anything else someone knows that I can check out?

I don’t know for sure so this could be a really bad guess. Does your trailer have backup lights? If so - I have no guess at all. If not - I’m guessing the 7-pin on the trailer side wouldn’t have anything telling the Magnum rack to do anything.
If a terrible guess - my apologies!
