This wiring harness is ready configured for the speedo units Acewell 4453, as well as our handlebar switch kit made of classic cast aluminium and therefore plug+play mountable. Since a circuit diagram is included with the delivery, the reconfiguration to other switch units is also possible without any problems. If you want to choose both speedometer and handlebar switch, you can order our universal wiring harness.
The extensive BMW electrics from the lamp are omitted, which is especially advantageous for individual front conversions. Nevertheless, the wiring harness also fits all two-valve models with a narrow tank tunnel. A new starter relay is included with all wiring harnesses. A 0. 1-90 Watt flasher relay, independent of the load, is also included with all wiring harnesses, with the exception of the Racing wiring harness.
The SE wiring harness completely replaces the BMW main harness and fits plug+play to the connectors of the original BMW engine electrics. The original BMW relays and the original BMW Sicherrungskasten is no longer needed. Only turn signal and light must be connected individually.
You can use the SE Aluguss handlebar switches or by means of the adapters SE-60-20108-01-002 (adapter cable can only be used for Monolever models) to connect to the original handlebar switches.
All wiring harnesses are supplied with a clear circuit diagram. This is helpful if you want to make further changes. The original BMW cable colours are always used.
