the wire harness for the radio is cut will that keep my headlights from working i have parking and brake lights but no headlights 89 camaro 2.8 v6

 

no, the wiring for the radio contains no wiring for the headlights, however, if the harness was cut while the lights were on, it can blow the fuse for the guage cluster\interior lights, but not the headlights. it sound like the headlight relay under the hood is bad
