What is the fuse # XXXXX and how many amp fuse?
Since you know electrical diagrams this shouldnt be a problem for you....here is the diagram for that circuit, let me know if you have questions. thanks.
According to my diagram there is no possible way for fuse to blow when headlights are turned on if relay is removed....I'll opt-out of question to see if someone else has some ideas. Someone will respond automatically so dont reply or question will be locked to me only. thanks.
