So a little while ago, I picked up a 83 Honda 200m. Plans on getting running and using it as a work horse and a ride. Starting to part out a 85(I think) Big red because it was gone. But it turned into a motor swap. I have it in and almost back together and I saw a wire hanging out the back of my transmission. What does that control and does it need to be plugged in? Sorry I can’t provide a pic of it.
