I got running lights but no brake or signal lights......

I purchased a 7flat pin circuit tester to find out if my trailer wiring was messed up or if its on the truck end. It seems its coming from the truck side. I have an 08 toyota tundra and if anyone might have a clue what could be the problem i would greatly apprieciate any info.

I checked all the fuses and they are all good. im lost!!! I dont want to get a ticket, at least the running lights work...
