I am trying to wire up my Hella fogs to the factory wiring so I can use the stalk/switch on the steering wheel in order to free up one of the dash cutout for the air locker switches. Does anybody know which wire is positve and which wire is ground? The colors are white with green stripe and the other wire color is red or I think orange. I only have one cutout left due the foglight switch and clutch engage switch. Thanks for the help.
