I bought a 2003 Harley Gauge cluster for my 2001. my truck is in KMS but the new cluster is in miles......no big deal. I swapped my rear board and odometer with it so it would work in my truck and run....but the speedo is way out. If I return it to normal and have my pats programmed for it will the speedo be right on? It looks really good and I love it but i am using my GPS to tell me how fast I am going right now. any help would be great. How much does it cost to get the Pats programmed?
