With custom wiring harnesses with micro buttons on the handlebars, the mechanic often is faced with the same question: Where to put the relays? The buttons themselves do not stand high switching currents.
The programmable control modules from Axel Joost Elektronik combine the basic bike functions (horn, load independent turn signals, head light, starter) in one box and eliminate the need for relays. The Version D additionally offers brake light and engine start/stop control. Control is via thin cables to the buttons on the handlebars, the outputs switch the electrical loads. The turnsignals and lights are programmable to a certain extent:
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.
