That extra wire is for the hand grip warmers ,in 84 they added an extra 30 watt coil just for the hand grip warmers. The 84 engine will work just fine , if you have hand grip warmers on the sled just run a wire from the warmers down to the extra wire and that way your warmers won't dim your headlight when you have them on. I would just unhook the existing power wire at the grips and hook them into the extra wire. I have an 83 and before I updated to the newer stater when I had the warmers on at night the head light would dim there wasn't enough power to run the light and the warmers, that is why Yamaha added the extra 30 watt coil , the 83 had 120 watts and the 84 & up had 150 watts. If you don't have warmers just leave it alone. I hope this helps.
