Im having a problem regarding my 2004 polaris sportsman 500 spedemoter cluster. my ATV got rolled quite a while ago and i am now just able to replace the spedemoter that broke. i went to put in the brand new spedemoter and it still dosen't work. i noticed that in one of the electrical things you plug in to the back of the spedometer was missing 3 small silver pieces. on the back side where the wires go in theres 3 blue plastic little pegs that go up halfway or so and i have no idea why those would be there. would missing those 3 little pieces be the problem?
