There may be a shorted tail light bulb circut. Try changing your bulbs first and if that does not work test all the pigtails for continuity and shorts with a circut tester. Check for pinched wires to the tails lights or any wires near the brake pedal.

Have you recently replaced any tail light bulbs? Make sure they are the correct type


It could also be a bad ground at the tail lights. Have someone step on your brake pedal. If the brake lights are dim it's the ground. If they are bright it's a short.

Also check to make sure all your fuses are good. A bad fuse makes weird things happen.

Check your brake light bulb. Had the same thing happen to me and found the filaments inside the bulb were touching, thus everytime the brake was pressed it was backfeeding the lights.

That could definately be your problem. You might disconnect all that and put it back original. If you need trailer wiring, start with a clean slate so you can get it done right. This is a common problem and happens a lot.
