Hello, I am in the process of replacing the original electrical combination switch on an Ossa TR77 350. The wires from the motorbike are not matching with the wires on the e combo switch both in colour and in number. The supplier of the e combo switch provided information on the new colour codes but I am having some problems to fully identify with what wires they must be connected on the bike. Anyone have a wiring diagram for the TR77 please? Thanks Adrian.
