Electronic Modules Custom

Ultra-compact switch box which is small enough to fit into most headlamp shells. The MD Cycle Control unit allows to operate starter, hi/low beam, horn and turn signals by means of micro button switches from your handlebars. It is compatible with all types of turn signals, including LEDs.

There are many control modules for the electrical system of a Harley-Davidson custom bike. These modules can be operated via pushbuttons on the handlebar and do not require bulky switches. These modules replace relays and centralize electrical functions such as lights, horn, etc., into a single device.
The mo.unit blue from motogadget, however, operates on a completely different level. Not only does it switch all electrical components on and off, it also protects all circuits, eliminating the need for fuses except for a main fuse. It can be operated with pushbutton controls or with conventional, mechanical handlebar switches. The wiring harness is greatly reduced to just the cables running to the loads and very thin wires to the switches/pushbuttons. If you additionally use a Further information on wiring, programming, and additional parameters can be found in the linked user manual.

Further reduce and simplify your mo.unit based wiring harness by using this little mo.button device. Installed into the handlebar tube - or any other adequate location - this tiny cylinder will electrically connect all handlebar instruments, switches and buttons. With state-of-the-art bus technology, the mo.button digitally processes signals and transmits them to the mo.unit V.2 over a single thin wire. The electrical consumers will then be switched inside the m.unit. All control wires are moved into the handlebar. This saves space, weight and time. A must-have for custom bikes with clean-look handlebars.
The mo.button is completely moulded, making it water-tight and resistant to vibrations. It has connections for
turn signals, headlights, starter, horn, brake light switch,
and can only be used with the mo.unit.

The younger your Harley, the more complex the wiring — at least if you keep it stock. But when doing a custom build, you can definitely simplify the electrical system. Not necessarily just to cut down on relays — since with micro switches on the handlebar you can’t really do without them. After all, those switches aren’t designed to handle high currents directly. But you can take the load off the switches, centralize the wiring, and reduce it all to a cleaner, more functional harness with fewer cables.
The programmable control modules from Axel Joost Elektronikbox combine the basic bike functions (horn, load independent turn signals, head light, starter) in one box and eliminate the need for relays. Control is via thin cables to the buttons on the handlebars, the outputs switch the electrical loads.
The minimal size of the boxes allows a mounting in the head light shell, under the tank or hidden under the seat ... in short: everywhere on the bike, where there is just a little space.
A not to be underestimated advantage beside the saving of the relays is also that the modules simplify the wiring of custom bikes substantially and one gets along with very few cables.
The modules are sealed waterproof and are delivered with a blade type fuse.
Who wants to activate basic lighting functions, the horn and an electric starter, should choose the H-Box.
These are the functionalities:
Horn (push button), Engine start (push button), To start the engine all other electric consumers can be switched off (saves battery power), Turn signals left and right (push buttons or switch), Turn signal cancellation programmable, Turn signal can work as position lights, High and low beam (push button or switch), Circuit function control via LEDs,
The current version of the H-box incorparates the possibility to manage all circuits via just two push-buttons. Just look up the under "Documents" for more information.

The D-Box offers - compared to the H-Box from the same brand - enhanced features that can be relevant for security functions on more recent bikes. Here's a list of the D-Box's functions and circuits:
Turn signals left and right (by push button or switch), An extra wire for the turn signal indicator LED (safes you wiring diodes or LED-adapters), Turn signal cancellation and position light function programmable, High and low beam (by push button or switch), Horn (push button), Brakelight (push button), Engine start (push button), Ignition power supply, Neutral and sidestand switch can be used as security circuit, Emergency switch (kill switch by push button or by switch), LED equipped function control for all circuits,
The D-Box can be used together with the OEM TS(S)M. This feature will preserve speed-dependent turn signal cancellation and the alarm system.
There is also a small device called D-Box adapter that takes all the pulses from the handlebar push buttons and passes them on to the D-Box via a one wire bus. This way you will be able install the D-Box under e.g. the seat and just route one single wire to the handlebar, instead of a wire loom made up from at least six wires.
The friends of super-tidy handlebars will be pleased to know that the eight functions of the D-Box can also be programmed to be operated with just two handlebar buttons. The box will work with just the turnsignal button-switches then. Press the left or right button one time or two times briefly, press them one time over 0.3 s or press them both simultaneously to activate the indicators, main beam, ignition, horn and starter relay or hazard lights. (More on this in the instructions - link under the picture bar.)

On recent Harley models the complete electrics and electronics are managed by two or three computers: the ECU for the entire motor management, the ABS module - if so equipped - for the regulation and control of the brakes, and the Body Control Module - in short called BCM -, i.e. the computer that manages the whole communication between switches and buttons, lighting, instruments, and indicators. A brief example: it's no longer the brake light switch that commands the brake light in the rear of the bike. The brake light switch just sends a pulse to the BCM, which then in turn lights the bulb.
All three computers communicate with each other by means of a data bus, the so-called CAN-bus. The customizers' nemesis now is that the BCM can only work with pulses and signals from OEM switches and buttons, and that only OEM instruments and indicators can correctly interprete its data packets. All in all rather swampy ground for successful customizing.
Here the TLT-Moto CAN-switchbox enters the scenery. It works with custom switches' inputs, provides the correct signals for custom speedos and tachometers, switches on indicators, and takes over the entire communication with the BCM. This in turn doesn't even take notice of the bunch of foreign stuff around it, presumes to be working with OEM periphery, and your Harley runs as always, with no error codes or vehicle-downs.
The CAN-switchbox has - besides power, ground and bus-connections - 11 input and 9 output channels and provides 6 switched grounds for indicator LEDs. Connecting the CAN-switchbox is no big deal, but requires a bit of care. And previous experience with electronics is welcome.

If LED indicators are mounted on Harleys with HD-Lan (CAN-Bus), the flashing frequency must be adjusted afterwards:
by adapting the software of the BCM, by connecting in resistors, or by connecting a Badlands load equalizer,
Despite these measures, the indicator light in the dash may still flash with the wrong frequency, and this is where the i.Load-IL1 comes in. As the turn signal circuits are completely separated in the Harley BCM, one module is used per pair of LED indicators (rear/front), the connection is relatively simple.
The module is not model-specific.

If LED indicators are mounted on Harleys with HD-Lan (CAN-Bus), the flashing frequency must be adjusted afterwards:

However, the dash board indicator lights of recent Harley models that are HD-LAN equipped can signal an error, meaning that either the turn signal light frequency is not correct or the error warning light will light up.
To avoid these problems, there's the Kellermann i.BOS module. The five wires are connected to the turn signals, the brakelight and ground. The device itself can be bolted anywhere thru its mounting tag or tied to a frame tube with its ingenious curved section.
The module is not model-specific.

When you convert from bulb turn signals to DF LED turn signals on 2018-2020 Softail models, you have issues:
The flashing frequency is no longer correct or the LED units glow continuously. In addition error messages and malfunctions of the indicator lights appear in the dashboard.
The i.LASH HD2 corrects all these problems and ensures that the flashing frequency is correct and no error messages are displayed on the instruments.

More and more bikers are using their cell phones as navigation devices — thanks to Google Maps. Nobody worries about permanent transmission of location data 'cos after all, you have a flat rate with 50 Mbit/s of download speed. But one thing is clear: using your smartphone as a sat nav permanently drains the phone's battery and can work effectively only if you hook it to a charger on your Harley.
For all those who do not own a FLHTCU with a built-in USB port, this practical USB socket could be used to charge the cell phone. The socket is waterproof (as long as not in use!) and is mounted on the handlebars, the 12V/5V voltage converter and the 12V supply cable can be tucked away under the gas tank. Connection options are available at the battery terminals or on live wires — haha — via the supplied connectors.
Of course, the socket also charges the smartphone if it does not have to work as a navigation system.
