We are on our first trip with our 2016 Bighorn 3570RS. After hooking the 7-pin connector to the truck, the brake lights and turn signal lights work fine. However the running lights / marker lights and tail lights do not work. They should come on when I turn on the headlights on the truck, but they do not.
As this is our first trip, I don't know if they ever worked. This was not something I checked during PDI (I checked the brake lights of course but not the running lights as it was full daylight at the time).
As all of these lights don't work, it must be something on the whole circuit. I am going to check the following:
Any and all help would be appreciated.

Thanks!

- Is this fuse blown on the truck? (Not likely but somewhat easy to check)
- Is a fuse blown / circuit breaker tripped in the fifth wheel? Not easy to check as I don't know where the fuse panel is. Behind the basement wall, near the steps perhaps?
- Maybe the 7-pin cable that runs from the fifth wheel to the truck is bad?
Any and all help would be appreciated.
