-Beginning in 2004, the Vehicle Speed Sensor (VSS) feeds its pulses to the ECM (not directly to the speedometer). The ECM interprets the pulses and sends a digital stream of data, using the Serial Data Bus, to the speedometer & the TSM/TSSM related to the operating speed. The speedometer takes the SDB data and converts it to the necessary impulses to operate the dial needle to show the current speed. The TSM/TSSM uses the data in evaluating when to cancel the turn signal function.

-The Speedometer 'marries' to the ECM (when new after 30+ miles) and thereby may prevent the speedometer from being moved to another bike or another already-used speedometer being placed on this bike. This is related to preventing turn-back of the mileage reported on the odometer. The odometer information is stored in the speedometer.

 **2011-later** - All Custom model Sportsters received a new, self-contained, LED Tail Light assembly (P/N 69352-11A). The LEDs are integrated into the lens assembly and cannot be replaced separately. Non-Custom Sportster models thru 2020 (with a center tail light) continued to use the distribution circuit board & the #3157 type bulb. Other Sportster models implemented brake lighting using the LED Turn Signals and had no center tail light.
-**2014-later** - The under-fender wiring was changed when the CANbus controllers were implemented. Two wiring colors changed and causes some confusion because the wire that is RED/Yellow color is used differently in those years. The other four wiring colors & functions remained the same (into the same version distribution circuit board).
