I was able to get my tie downs straight thanks to everyone. Now I found a new thing. My
Old camper plugged into the truck. I thought this one did not. But then I found a small round outlet with 3 pins. I have searched everywhere and cannot find a cord to plug Into my truck. Has anyone used a 3 pin plug and adapter to 7 pin?

It's probably a short unit that doesn't block the tail lights, so it like only has 12 +/- for cabin power, plus a marker lights circuit.

Thank you. After I posted I thought of a shell with a high mount brake light...

If it's old probably not a high mount brake light . More likely 12v interior light , marker lights and ground . Easy enough to check .
