I haven't studied the wiring on my Daytona, but on my TB the indicators are hooked up to single connectors front and rear. And since they share everything else (I run a Daytona ignition lock, Daytona engine electronics, Daytona indicator relay) I can only presume the wiring harness also is the same for indicators. If memory serves, you should find one green and one black for one side, and one green and one grey for the other. Regardless of colours, it should be two of the same colour and one each of another
Of course, it could be that Triumph for some reason chose to have just the connectors for the indicators made differently in the harness, making my information useless
