I have the new Analog combo speedo/tach part # 70900072 I want to install on my '09 Heritage classic. This speedometer was on my brother's 2010 Heritage & I inherited over the winter when he upgraded to an Ultra Classic. I finally found the data connector under the seat for the speedometer on Saturday morning and hooked everything up as per the instructions. It said it would take a bit to transfer the info & it would say when done. I had a red light on the lower right of the speedo come on for about 2 seconds & that was it. The speedo is still showing his mileage. I didn't want to install the new one & find out it wouldn't pick up my mileage. After a couple of trys I got the message VIN ERR, looks like the speedo is still tied to the previous bike. I had this message from another form : That speedo gets married to the ECM after 1000 miles. It will only work properly on your bother's bike. Any ideas? , may have to make a trip to the dealer.
