Turn signal toggle switch question

[LizardsA]

Good day folks,
I am trying to wire in a turn signal toggle switch, but need advice please on where the wires go.
As you can see from the accompanying picture, the toggle switch has place for three wires to attach. The flasher unit also has place for three wires to attach.
Please can someone help with a simple explanation, or a simple diagram to show me what to do?
Kind regards
