I am making a mockup for my running lights before i wire it permanently.
From the connector on the truck I can get the right and left blinker and brake lights to work but I can't get the tail lights to come on (when I turn on the headlights). Is there something different about wiring the main lights?

i had the same issue but it wasnt just the fuse, the trailer has a short in its clearance lights that caused my running lights (because they were on the same line) to not work. I had blinkers and brakes but no running. I have not had the time to look into it yet (because it looks like that will involve pulling some paneling back down. suspect a screw or something is through a line somewhere... ugh! however we cut and capped the feed line to the upper lights. this allowed the taillights to work correctly, just no clearance lights/side lights. We generally do not run at night anyway so its usually not an issue.
If you can't fix it with a hammer you have an electrical problem.
Before you pull panels down, try pulling the lights from outside. There is a possibility of a wire cut and grounded where it goes through the skin. It may be a simple fix that won't require a lot of dismantling, just a lot of time and patience to find the culprit.
