I just wish I could read those things. I'm like a blonde looking at a road map when it comes to electrical schematics.

Should be the brown wire running to the back of the 7 way for trailer running lights IIRC. Sounds like you have partial function if the stop and turn signals are working so I am guessing you have a bad connection or burnt wire just on that one circuit. Test the individual prongs on the truck outlet with a test light or buy one of those circuit testers from an RV or trailer shop for $20 or so. (Handy dandy little tool). Not sure I'd recommend running the whole trailer running lights off the license plate light circuit. It could be okay but if the amperage is too high you can blow the fuse or melt the wiring on that.

They've never done me much good either.

Unless the plug in the pickup bed was factory wired it's usually maximum cringe factor when somebody hacks into the factory wiring to add the bed plug.
