Was taking out the Cluster and didnt know that there was a 1 inch Speed wire or a speed sensor wire that was connected from the Tranny to the MPH Tach (that was a B taking it out/in) got everything in, and the MPH started to Act up and going 5 MPH it jumped to 110 to 120 and was just clicking, took the MPH Tach out and found out that the Adapter on the Tach was Cracked and was just Turning. so i would need a MPH Tach or the whole Cluster for my 97' Impreza
