BMWlunchboxadapter Axel Joost Elektronik, BMW K ''Lunchbox Adapter''

Converting an older BMW K-series bike to a modern speedometer can be a wiring nightmare, but this Axel Joost Elektronik Lunchbox Adapter makes the job straightforward. It plugs into the original harness connector where the old factory instrument cluster used to live, providing ten output cables for all your necessary signals. It handles the conversion for the neutral signal to work with modern gauges and even includes a built-in virtual load for the alternator, which is essential for the charging system to function correctly without the stock bulbs. For models up to 1985, it also integrates the fuel reserve signal. Housed in a waterproof, shock-resistant ABS case, it is a compact and reliable solution for any K-bike custom project.
