2009 Peterbilt 384 light nightmare! Help!

So yesterday I went and pickup up a new used trailer and it has some loose wires crossed in the female plug on the trailer that I did not know about so when I plugged into it it popped all the lights on my truck so I put a new plug on the trailer and went over every fuse in the kick panel to the left of the clutch peddle with a test light and replaced every blown fuse I could find now all my running lights work and my right blinker works but I have no left blinker truck or trailer with trailer plugged in or unplugged and I have no brake lights truck or trailer from the foot brake nor the trolly I have no clue what could be going on with it also the 4 ways only flash the right blinker anyway have any ideas??
