LED tail lights on '04

My '04 has LED tail lights I didn't install them myself, they were already on the truck when I bought it. My right brake lights are only half power, my left is fine. I know that there is a short somewhere in there because when any of the 4 doors are opened the brake lights flash. Does anyone know of any quick tips on fixing it? Or am I going to have to rip the wiring out and redo it all over again, or would it be cheaper/easier to just go back to stock lights again?

I'm not too concerned about this issue yet because the cops haven't pulled me over and given me a fix it slip, but I'm planning on fixing all 3 issues with my truck at the same time.

Thanx in advance!
