speedo question
i swapped out my instrument cluster yesterday with a better looking one, the circuit board on the back was a lot better shape than mine so i switched it out, just the cluster and the only thing i kept from mine was the speedo so that way i could keep the mileage the same, now my speedo is jumping all over the place....what could be the cause of this? the circuit board was a little different than mine but from what i could tell it only affected the oil pressure gauge (the person before me rigged one in there)
