 The CANbus Key Switch has three positions - OFF, ACC & IGN - There are only two wires used for the three functions. When OFF, the two wires have no connection. When in ACC Mode, the two wires are connected by an 800 ohm resistor, which provides a HI signal to the BCM. When in IGN Mode, the two wires are connected by a 200 ohm resistor, which provides a LO signal to the BCM. In this way, the BCM can determine the switch mode and implement the appropriate control of the various circuits. The CANbus Key Switch has three positions - OFF, ACC & IGN - There are only two wires used for the three functions.

 The Front Brake Switch is installed between the brake lever & the master cylinder assembly. It is a normally closed switch, but the contacts are actually held open when the lever is not being pulled. When the lever is pulled to activate the front brake master cylinder, the brake switch is no longer pressed by the lever, the contacts now close and power is sent to the rear brake light. This switch is often damaged (causing the brake light to stay ON) by not paying close attention to the following caution from the manual regarding disassembly & assembly of the master cylinder or brake lever or right switch housing: The Front Brake Switch is installed between the brake lever & the master cylinder assembly.

-The Rear Brake Switch is installed in the rear brake hydraulic line from the master cylinder to the caliper, typically on the left side ahead of the caliper. It is a hydraulically activated switch, meaning that at a certain level of hydraulic pressure in the brake line, the switch closes to conduct power thru it to the rear brake light.

-The speedometers were rated as 2:1 ratio, meaning that for 2000 RPMs of the cable, the speedometer would register 60 MPH. All Sportster model speedometers from 1973-1994 were front wheel driven and used a 2:1 ratio. From 1957-1972, the Sportster speedometers were cable driven from the transmission,​ but they also used 2:1 ratio speedometers.((http://​xlforum.net/​forums/showthread.php?​threadid=1545261))+The speedometers were rated as 2:1 ratio, meaning that for 2000 RPMs of the cable, the speedometer would register 60 MPH.

 From 1973-later, the 19" front wheel meant that the wheel driven unit for driving the 2:1 ratio speedometers all used nearly identical ratios for converting wheel rotation into cable rotation, approximately 1 wheel rotation = 2.625 cable rotations. From 1973-later, the 19" front wheel meant that the wheel driven unit for driving the 2:1 ratio speedometers all used nearly identical ratios for converting wheel rotation into cable rotation, approximately 1 wheel rotation = 2.625 cable rotations.
  
-Normally, for 1984-1994, the wheel driven unit will be a match to the speedometer - that is, a driven unit intended for 2:1 (67127-84A - which creates a 1:2.625 ratio of wheel-to-cable rotations) is used with a 2:1 speedometer (likewise, the drive unit and speedometer would be matched for 1:1 or 2240:60 on the BT). However, if you use a 21" wheel/tire on a model that original had a 19" wheel/tire and used a 2:1 ratio speedometer (as stock on all pre-95 XLs), then you need to use a wheel driven unit (FXLR - 67132-85A - that creates a 1:3 wheel-to-cable ratio) which was originally intended for a 2240:60 ratio speedometer. This makes the 2:1 ratio speedometer read close to the right speed.

 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. Beginning in 2004, the Vehicle Speed Sensor (VSS) feeds its pulses to the ECM (not directly to the speedometer).

 Pre-2004 HD Tachs used a pulse signal input and were designed for use with dual-fire ignition systems. The non-SPORT models used the trigger signal for the ignition coil (typically, PINK wire) to also trigger the tach. The SPORT models, which have a single-fire ignition system, used a tach trigger signal generated by the ICM (separate from the coil triggers) that is intended to drive a tachometer that is dual-fire ignition compatible. The same OEM tachometer was used on the dual-fire 1200 models and the single-fire 1200S models. Pre-2004 HD Tachs used a pulse signal input and were designed for use with dual-fire ignition systems.

 + 
 +**1999-2003E** - A new distribution circuit board was added to the tail light assembly. The turn signals & tail light all connect here. The main wiring harness uses the under-fender sub-harness to provide power & control signals to the distribution circuit board (See Diagram for detailed connections). The connector on the (2-pin) right rear TS cable is BLACK while the LEFT is WHITE. Tail light / brake light uses a (4-pin) BLACK connector. 
 + 
 +**NOTE:** There have been a number of situations where the Taillight Circuit Board becomes corroded and any/all contacts become intermittent or low-grade shorts. Because there is an opening from the fender to the circuit board area, it allows moisture (if not road debri) to cause oxidation. This is especially problematic if the bike is left outside or operated in the rain. It's a good idea to check & thoroughly clean this board and each connector with circuit cleaner at least once per year, using dielectric grease on the contacts.

 +**2014-2020** - 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).

-**NOTE:** There have been a number of situations where the Taillight Circuit Board becomes corroded and any/all contacts become intermittent or low-grade shorts. Because there is an opening from the fender to the circuit board area, it allows moisture (if not road debri) to cause oxidation. This is especially problematic if the bike is left outside or operated in the rain. It's a good idea to check & thoroughly clean this board and each connector with circuit cleaner at least once per year, using dielectric grease on the contacts.

-This module receives a positive signal from the left or right handlebar switch when pressed (these are momentary action switches). This begins the turn signal flashing function. The function continues as long as the switch is held down. When the switch is released, the module, in communications with the speedometer,​ calculates the amount of distance travelled. Once the predefined distance is travelled, the unit turns off the flashing function. It will also turn off the flashing function within 2 seconds after determining (using the BAS) that a turn has been completed. If the right turn signal switch is pressed while the left turn signal is flashing, the left will stop and the right side will begin a flashing sequence (same if right is flashing & left TS switch is pressed).

 +**Testing Signals TO/FROM the TS Module (2000 Model)**\\
 +
 +For 1997-2003 the TS Module is part number 68540-96.

 +The TS Connector has these wires/​signals:​\\
 +1 - BLACK wire - Ground\\
 +2 - ORANGE/​White - Acc Power In\\
 +3 - BROWN - Right TS Flash Out\\
 +4 - VIOLET - Left TS Flash Out\\
 +5 - WHITE/Green - Speedo Cancel In\\
 +6 - no wire\\
 +7 - WHITE/Brown - Rt TS Switch IN\\
 +8 - WHITE/​VIOLET - Lt TS Switch IN\\
 +
 +DISCONNECT THE CONNECTOR TO THE TS MODULE.
 +Then test the signals on the harness connector.
 +
 +With a multimeter, BLACK PROBE on Pin1, you can use the RED PROBE to check for power on Pin2,\\
 +check Pin 7 to see if it gets power from the Rt TS Switch (when pressed),\\
 +check Pin 8 to see if it gets power from the Lt TS Switch (when pressed).\\
 +
 +With a jumper wire from Pin2 (if it has power)\\
 +jumper it to Pin3 to see if both Right TS lights are ON,\\
 +jumper it to Pin4 to see if both Left TS lights are ON.\\
 +
 +THOSE TESTS do not check the TS Module - they check everything connected to the TS Module\\
 +to see whether they DO OR DO NOT WORK. If all that works, then the TS Module is suspect.\\
 +
 +Use the correct pinouts for other year TS Modules to do the same type testing.
