ok so my friend gave me all his wiring to his old fog lights for replacing them for him. i now installed them into my ef connected into diff fogs. but they didnt turn on. i soon inspected the fuse and it seemed like it just needed some scraping cuz it seemed like its startin to rust up. but that didnt help. i believe its the relay but how can i be sure? plz help. ( im 100% sure i connected the wires right)
