ok well i got done replacing my stereo and crank my car, and now the abs light stays on and the brake light and low trac light goes off and on and whenever i rev it up about 3 grand it comes on and goes off? does anyone know what the problem could be by any chance?

 

If this is on a 4th gen F-body????? Check the ground wire on the passenger side fenderwell...Its close to the positive connection terminal(red box).....

 

ok yes its on my 96 trans am

 

the only wiring that interfaces with that comes from your illumination circuit (orange wires). cap those off in your wiring harness and that MAY resolve the issue.
