I have a cargo trailer and I want to wire the interior lights that are in it, the lights are hooked up to a switch so you can turn them on or off, but what I want to do is have them where I can turn the lights on without having the truck lights on. But if that means running more wires from the truck then I can't do that. But if you have a wiring diagram I could use then that would work.
If you have a 6 or 7 way plug you should have a battery (hot) terminal to feed the light switch. If it is a 4 way plug, there are only light circuits. If you have a ford, the battery terminal will usually only be charged when the vehicle is running.

Add a battery to your trailer to run the lights...so you don't accidentally run your truck battery down to the point of not being able to start your truck

Many vehicles and/or travel trailers use the aux as reverse lights. Many travel trailers have real back up lights.
I have seen trailers equipped with batteries and say a winch, use the
aux as a additional/heavier battery charge line.
For a while Bloomer and Kiefer called for it to be a 12V hot (may still do?). Bloomer uses it to power the elec/hyd brake actuator. Dexter had Kiefer do it to power the air ride compressor on the Dexter air ride system.
Most "regular" horse and livestock trailers don't use it at all. Most factory truck wiring will have it as a reverse.

We don't have batteries on our trailer and we use the 12v to power the interior lights on the trailer. It is 12 volts continuous feed. The big caution here is that on a ford, the truck has to be running. Using a test light check your truck socket to see if it is hot with the key off.
