Brakes

You have a grounded wire in that circuit. Check the wiring in the trunk to see if you can locate a pinched or misplaced wire, also if you have installed any aftermarket stuff under the dash check to see which wires you tapped, I hope this helps. Take care

Thanks so much for taking the time that's what i had read that maybe a wire but where exactly is it located in the trunk? And I haven't i haven't installed anything in the truck please give me feedback thanks ☺

The tail lights and brake lights are 2 totally separate circuits the brake light fuse probably blows the first time you step on the brake pedal the first time after changing the fuse, if it takes a while for the fuse to blow I would check to make sure the bulbs are the right number and the fuse is the right amperage. You can install a circuit breaker in place of the fuse then hold the brake on for about 30 sec then start to feel for warm/hot wires under dash and trunk the hot wire will lead you to the problem
