Running Lights don't work
We have a travel trailer with & a brake controller in our car. The brake lights and the turn signals work on the trailer, but NOT the running lights - what could be wrong?

Maybe the OP needs this presented a little clearer and simpler.
The brake LIGHTS and turn signals work off one connection in the pigtail hookup
The TAIL lights and clearance lights work off ANOTHER different connection
The BRAKES themselves are yet another different connection.
Three pin connections, and three electrical circuits are needed for the three functions above.
Now if your TAIL lights in the trailer work but not the clearance or marker lights, that's a horse of a different color.
You could help find the answer by re-examining the trailer lights to see if the tail lights are working as well as the brake and turn signal lights.
