Matching adapter for different bikes.

All bikes with SINGLE handlebar switch, use signalMinder controller SM-2134. The 3-pin input plug of the controller allows different pin-outs to match with different bikes.

For instance a 2-pin, 3-pin or a 5-pin plug.


  • DO NOT order this separately when you select signalMinder SM-1, SM-2, SM-3, SM-3N, SM-3S. SM-3R or SM-4. Appropriate adapter is included in that package.


  • Order ONLY as a replacement or if you've changed your bike.
