brake lights not working and stuck in park

Ok I'm trying to get rid of this damn tacoma. I swear this thing has been hood rigged way too much. So here's the deal, I tried hooking up a trailer connector to my 99 toyota tacoma (mistake). Either the wiring got messed up or the trailer wasn't acting right cause I'd end up blowing a fuse all the time and not having brake lights. Anyways there is a wire that would attach to a fuse in the fuse box under the steering wheel. Somehow that wire melted and when I went to grab it to check it out the whole thing just broke off. Ever since that wire broke no brake lights and stays stuck in park although I can push the override button. No Idea where the wire was coming from..I'm fucked.
