I'm sure that the answer is right in front of my face, but everytime I search for my issue I get 2nd gen solutions. I can't find anything for an FD.

My taillights don't work. By that I mean the constant lights when my headlights are on. Brake lights, hazards, turn signals all work. I read something about the headlight switch/harness going bad, but that was for a second gen. Relays up front are all good, fuses are good, brake switch for the pedal is good.

I've deleted my cruise control, could that have anything to do with it?

 

Deleting cruise shouldn't be a factor, unless you went hog wild and cut wires or something.

Do your license plate lights work? They are on the same circuit, same with the side markers. There's a TNS circuit - Tail, Number, Stop - that is for those lights.

You'll need to get the shop manual and a multimeter and troubleshoot.
