I got 03+ Tail lights with the harnesses from the stealership today. Almost everything works (flashers, blinkers, reverse lights). The only thing that doesn't work are the brake lights when I push the pedal down. I thought they were plug and play? My truck is an 02.... any ideas for why my damn brake lights dont work?

My truck did the same thing. my rear brake light fuses (yes 2 of them) were blown out. I spent nearly $60 tryng to fix this problem and it was a damn fuse. Try that and see if it fixes it.
