I have never done one but it can't be that hard. Remove the bezel around the cluster. It should be held in with screws. Remove the screws holding the cluster in. I am not sure if they have a speedo cablr or if it is electric. If a cable there should be a clip that you push. Grab the cable going into the back of the speedo. Push the retainer and pull cable off. If electric disconnect plugs. Like I said I have never done a tracker before. Just tell my past experiences with other vehicles.
