I don't want to sound dumb but her goes. I have a 3 wire GM alt, I know the one wire goes to the battery and the 2 pin plug one goes to the Horn relay and the other one is for the idiot light. here's my question, if I do not have an idiot light what do I do with that wire ? I have looked on the internet but have not forund the awnser, so I came to the place that can give me the awnser.
