INSTALLATION - CONNECTIONS OVERLOOK
Once all cables are in place, these need to be connected to the ECU.
The Handlebar Control Unit cable has a fixed Higo connector at the end,
and the connection is made directly onto the ECU.
The LED units' cables are supplied with extra length, and these, if you wish,
can be cut to size.
Each LED unit cable is marked with a red sleeve, which indicates the LED's
positive polarity.
If you wish to cut any LED cable to size, make sure you mark the positive
polarity prior to the cut.
Inverting polarities won't damage neither the LED unit, nor the ECU unit.
The result will be a non blinking LED unit, and the connection to the
ECU will need to be re-done.
