There is a green and brown wire from puck to speedo. If they are changeable go for it just for fun. Even change on the back of the speedo?

Believe sensor is just a magnet. Metal thingies from the trans pass over it creating a pulse. You can't fry anything reversing wires. Is this possible?

Continuity test from trans to speedo is advisable. Also low DC voltage test at puck may be a good way to see if there are blips but I don't know how to do this without starting engine and putting it in gear and even then not sure if that would work.
