I bought a jdm s13 cluster and installed it along with a new dash over the weekend. When I started the car the needles stayed exactly where they were when I bought it. The speedometer is pinned at 180km/hr and the tachometer is also pinned. Is there a easy way to "reset" it. I really don't feel like pulling it apart again. Thanks for any input
also, the 3 connectors were plugged in so rule that out
