Wunderlich wire harnesses for classic BMW Airhead-Boxer
In conjunction with our handlebar switch made of cast aluminum they are delivered ready to install (optional available see below).
The extensive BMW electric system from the lamp falls away, which is particularly advantageous for individual front conversions. Nevertheless, the wiring harness also fits on all two-valve models with a narrow tank tunnel. A new starter relay is included with all harnesses. A load-independent turn signal relay 0.1-90 watts is also included in all harnesses, with the exception of the Racing harness.
All wiring harnesses are delivered with a clear circuit diagram. This is helpful, for example, if own handlebar switches are installed. For the general use of other speedometers, handlebar switches, etc. we offer a universal wiring harness. Of course, with a detailed circuit diagram. The original BMW cable colors are basically reused.
For the racetrack, we also offer a reduced, ultra-light racing harness, which we have for reasons of weight on all wiring for lights, indicators, horn, etc. waived.
