i got an si cluster to put in my std, but i need to run the miles down on the new cluster to match the miles to my car, can i do this by using the port for the speedo cable?
this is true. i think there's like 3 or 4 screws on the back. loosen them and it should pop out. then you can just swap.I can't tell you how to reduce the miles. It's illegal
But you can swap the old speed to the new cluster.
