So as I begin getting all of my wiring in order and making sure everything in the car is working properly after my ls swap, I come to checking my rear lights. Well, when I connect the water proof connector in the trunk one set of lights come on (don’t go off unless I disconnect the trunk connector or the battery). My hazard lights work in the rear as well, as they should. Now I have no brake lights or turn signals in the rear. I have checked all the fuses and none of them are burnt/broken. Any thoughts from here?

 

What "set of lights" comes on? There are 4. Tail, brake, turn, or backup?

 

For the time being I seemed to have resolved the issue. When i was reinstalling the brake light switch and inadvertently disconnected one of my power lines into the fuse block. After finding the culprit and reinserted the wire and I seem to have all my rear lights back.
