Black/violet wire is the signal input for your tach. The Carrera tach takes a 12Vpp input signal. The MS ECU runs on 0-12V square wave. Though I Have never tried it, they should be compatible.
The black wire is the injector pulse width from the DME. It is not needed. It can be disconnected and taped off. Or left in place if the DME harness has been unplugged and removed during your conversion.
