Speedo help
i have a 2019 Road King, with a tank from a 21 Road Glide (no fuel gauge) I put a speedo for a 2019 FXFBS on and everything works but the fuel gauge. Trying to figure out how to make my fuel sending and bike communicate with the speedo. Tried splicing the wire from the gauge into the under dash harness but still no luck. Any help would be appreciated
