Dimmer Switch Wiring Question

[KYBlueOval]

I need some help with the wiring on the dimmer switch. I have an aftermarket wiring "Kit" and I'm going to need to splice  the new wiring into this OEM plug. I didn't take this car apart so I don't know how this switch is wired.
The Four Wires are as follows from left to right:
Red with Yellow Tracer to Left Terminal
Red with Black Tracer to Center Terminal
Green with Black Tracer 2 Wires, to Right Terminal.
I think the two green wires are for the Left and Right Headlight. But I'm not certain.
Any help will be greatly appreciated.
Thanks
John
