I wire tuck the headlight harness and everything in the front works but now my brake lights doesn't work....the lights in the tail lights turn on but when I brake nothing...it was working before I did the tuck cause I was bleeding my brakes and saw my lights working...any suggestion? Ty..yes I did check fuses and put new bulbs and everything is still good

 

Try testing by putting a ground right at the tail light and see if it works then.
Sounds like you are sure your power wires are all good - time to check ground!
