i hooked up to my horse trailer a few days ago and all my lights worked (except for the lights that are burned out) and i hooked up today and boom. i have one light. my upper right brake light. everything else is dead. havent shot wires yet for voltage but any thoughts? last time this happened i messed with the plug and it started working. well my messing around with the plug this time and only my one brake light works. any thoughts?

First Id check the harness to the trucks plug. Ive heard of them getting nasty. Also have you checked the fuzes under the hood? There are a few there for trailer lights.

Just a thought.
