I'm sure the same issue has been covered but every situation is a little different. Tonight I was trying to wire in my toolbox lights. Ran a ground wire from the toolbox to the ground on the taillight plug and ran the hot wire to the "minor" and "major" to see which was my turn signal and which was my tail lamp. Now my headlights will not turn off but I have no dash or taillights. But i have turn signals and brake lines. Headlight switch ? Checked all the fuses under the dash...no luck

 

What do you mean "minor" and "major" ?

Did you unhook everything you just installed and test again ?
- Need to have it back to factory, and make sure you did not damage the wires you were hooking up to.

How did you check all the fuses, and why are you checking all of them ?
- No need to check the fuse for the radio.
