I have a 71 hemi cuda clone and noticed a random blue wire coming from the alternator and going no wear. It has a plug at the end but is not connected. My car started out as a automatic 6 cylinder and was transformed into a 4 speed 426 hemi, see pics below,
could it be a wire for a AC compressor that way removed??

More importantly can I remove it???
