Multiple wire connectors obviously, just check that the wire color corresponds on the male and female connector.
Mostly the colors connect to each other. The left/right indicator wires can be confused. on my bike the wire coming out of the indicator shaft in the headlight bucket is black. Right side connects to the Dg, (Dark green) female wire/connector. Left side connects to the Ch, (Chocolate), female wire/connector.
Dark green and Chocolate wires can be mistaken for black if the wires in the headlight bucket are dirty.
Yellow, (Y), and Blue, (L) and Black, (B), will feed into a multiple connector,
Need to know the year of your bike. ...........If you are mismatched on years the connectors will be different, going from a 4 pin to a 6 or 3 to a 4. The looms changed over the years, a lot of extra wires got added
